The S-8813 Series is a PFM control charge pump DC-DC converter with a built-in constant-current circuit, and
was developed using CMOS technology. Its constant current output makes this series ideal as a power supply for
current drive LEDs.
The S-8813 Series features three output channels and can drive three LEDs.
This series is available in two types: a variable voltage type and a variable current setting resistance type.
Moreover, since small ceramic capacitors can be used as external capacitors (pump capacitors, input capacitors,
output capacitors), the S-8813 Series contributes to set miniaturization.

The S-8813 series controls by using the pulse frequency modulation (PFM) method. The SW1 to SW4
switching transistors are switched ON/OFF with the clock generated by the internal oscillator (OSC), and
operates the step-up charge pump.
The output voltage is feed back and the voltage split by feedback resistances Rs and Rf and reference
voltage (Vref) are compared by a comparator. This comparator signal is used to modulate the oscillation
pulse frequency in order to keep the output voltage constant.
Using this constant output voltage as the voltage source, a constant current is created using Vref and the
external resistance value applied to the RISET pin, and this constant current is supplied as the current
output to the three channels of output pins (IOUT1 to IOUT3). Therefore, even if the white LED VF
(forward voltage) varies between 3 V and 4 V, a constant current can be supplied, making it possible to
reduce fluctuations in brightness and keep white LEDs shining at a constant brightness.

2. Step-up Charge Pump
CT
The step-up charge pump steps up the voltage by switching ON/OFF the SW1 to SW4 switching
transistors.
First, in order to charge the pump capacitance (CPUMP), set SW1 to OFF, SW2 to ON, SW3 to OFF, and
SW4 to ON (charge cycle). Following charging the electricity, in order to discharge the charged electricity
to the output capacitance (COUT), SW1 set the switches as to ON, SW2 to OFF, SW3 to ON, and SW4 to
OFF (discharge cycle).
The input voltage can be stepped up to a constant voltage value by repeating this charge cycle and
discharge cycle.
In the S-8813 Series, the VIN voltage range of 2.7 V to 4.5 V is stepped up to VCPOUT = 5 V.

3. Constant current output circuit
CT
The S-8813 Series features a three-channel constant current output circuit and enables driving of white
LEDs in the current mode.
In the case of the S-8813 Series, the constant current value can be controlled using one of the two
following methods according to the product.
In the case of the S-881300CPE, the desired constant current can be obtained with an external
resistance value. Since a reference voltage of 1 V ±2% is output to the RISET pin, application of
resistance R1 of 20 kΩ to 5.6 kΩ between the RISET pin and GND results in the flow of a constant current
of 50 μA to 178 μA in the current setting resistance (R1) due to the I = V/R relationship. Amplifying this
constant current 100 times and outputting it to IOUT1, IOUT2, and IOUT3 can obtain a constant current of
between 5 mA to 17.8 mA/channel.

On the other hand, a constant current of the desired value can also be obtained for the S-881300BPE by
supplying the reference voltage to the VISET pin externally. Within the IC, a resistance of 10 kΩ is applied
between the VISET pin and GND. The application of a reference voltage of between 0.5 V and 1.8 V to
the VISET pin results in the flow of a current between 50 μA and 180 μA in the internal resistor (R2) due to
the I = V/R relationship. Amplifying this constant current 100 times and outputting it to IOUT1, IOUT2, and
IOUT3 can obtain a constant current of between 5 mA to 18 mA/channel.

4. ON/OFF Pin (Power Off Pin)
Setting the ON/OFF pin to the Low level ("L") causes the voltage of the CPOUT pin to change to the GND
potential and simultaneously the operation of all the internal circuit to stop. At this time, the consumption
current is largely reduced, to a level of approximately 0.3 μA.

5. Soft Start Function
NT
IN
UE
The S-8813 Series features a built-in soft start circuit. Upon power application or when the
ON/ OFF pin is switched from "L" to "H", the output voltage gradually rises over the soft start time,
and the output current is gradually output as a result. This soft start function reduces the input current
rush.
6. External Capacitor Selection
6.1 Input and Output Capacitors (CIN, COUT)
DI
SC
O
The input capacitor (CIN) lowers the power supply impedance and averages the input current, resulting in
improved efficiency.
The CIN value is selected according to the impedance of the power supply that is used. Select a ceramic
capacitor with a small equivalent series resistance (ESR). Although this figure varies according to the
impedance of the power supply that is used as well as the load current value, it is generally in the range of
4.7 μF to 10 μF.
For the output capacitor (COUT), select a ceramic capacitor with a small ESR for smoothing the ripple
voltage. A value of 10 μF is recommended for the capacitance value. Use of a capacitor with a
capacitance lower than 10 μF results in a larger ripple voltage as well as a larger ripple current for the
output current.
Conversely, use of a capacitor with a capacitance greater than 10 μF results in the output voltage not
being able to rise up to 5.0 V and the impossibility to obtain the desired output current.
6.2 Pump Capacitor (CPUMP)
The pump capacitor (CPUMP) is required for stepping up the voltage. Select a ceramic capacitor with a
small ESR. A capacitance value of 0.22 μF is recommended. Use of a capacitor with a capacitance
greater than 0.22 μF results in a larger ripple voltage as well as a larger ripple current for the output
current. Conversely, use of a capacitor with a capacitance lower than 0.22 μF results in the output voltage
not being able to raise up to 5.0 V and the impossibility to obtain the desired output current.

Output Impedance of the PWM Output Control Signal Source (RZ): Max.500 Ω
Calculation of IOUT According to PWM Duty Ratio: IOUT=1 V / (R1+RZ) × 100 × (1-Duty ratio)
DI
SC
O
Ideally, when the duty ratio is 0%, IOUT value is the 100 times value of the RISET pin voltage (1 V) divided by the
resistance of R1. However, the impedance from the RISET pin to the GND will serve as R1+RZ in actual operation.
RZ means the output impedance of the PWM control signal source when the PWM control signal is low level.
Therefore, the IOUT value varies depend on the RZ value.
Caution 1. Fix the PWM output to low level during standby (when the ON/OFF pin is low level). If the
PWM Output is set to high level, leak current will flow.
2. When the PWM duty is set to 100%, the current to the LED will be switched off. However, the
IC will still keep operation. This is not the same as standby mode, and so the current
consumption will be the same as in normal operation mode.
3. The duty ratio indicates the percentage of the high-level pulse width to one period.

Precautions
• Regarding the wiring to the VIN pin, CPOUT pin, C+ pin, C− pin and GND pin, be careful to perform pattern
wiring so as to obtain low impedance.
• Always connect a capacitor to the CPOUT pin, C+ pin, and C− pin.
• Connect CIN and COUT in the vicinity of the IC and sufficiently strengthen the wiring for GND pin and VIN pin
in order to lower the impedance of the wiring resistance, etc. High impedance may cause unstable
operation.
Moreover, in selecting CIN and COUT, perform a full evaluation of the actual usage conditions.
CT
• Connect CPUMP in the vicinity of the IC and sufficiently strengthen the wiring for the C+ pin and C− pin in
order to lower the impedance of the wiring resistance, etc. High impedance may cause instable operation.
Moreover, in selecting CPUMP, perform a full evaluation of the actual usage conditions.
OD
U
• The oscillation pulse width may be small with a light load; however, this causes problems in the IC
operation.
PR
• The ON/OFF pin is configured as shown in Figure 10 and is neither pulled up or down internally, so do not
use this pin in a floating state.
When not using the ON/OFF pin, connect it to the VIN pin.
Moreover, please do not impress voltage higher than VIN+0.3 V to an ON/OFF pin. Current flows for a VIN
pin through the protection diode inside IC.
UE
D
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
NT
IN
• Be careful about the usage conditions for the input/output voltages and output current to make sure that
dissipation within the IC does not exceed the allowable power dissipation of the package.
For reference, the calculation of the power consumption in this IC is shown below.
PD= (VIN ×2.0 −VIOUT1,2,3) × (IOUT1 +IOUT2 +IOUT3)
Reference: VIN=4.2 V, VIOUT1,2,3=3.6 V, IOUT1,2,3=18 mA
PD=(4.2 ×2.0 −3.6) ×0.054 =259 mW
