Description
The InnoSwitch? family of ICs dramatically simplifies the development and manufacturing of
low-voltage, high current power supplies, particularly those in compact enclosures or with high
efficiency requirements. The InnoSwitch architecture is revolutionary in that the devices
incorporate both primary and secondary controllers, with sense elements and a safety-rated
feedback mechanism into a single IC. Close component proximity and innovative use of the
integrated communication link permit accurate control of a secondary-side synchronous
rectification MOSFET and optimization of primary-side switching to maintain high efficiency
across the entire load range. Additionally, the minimal DC bias requirements of the link enables
the system to achieve less than 10 mW no-load in challenging applications such as smart-mobile
device chargers.

NOTES: A. This parameter is derived from characterization.
B. IS1 is an estimate of device current consumption at no-load, since the operating frequency is
so low under these conditions. Total device
consumption at no-load is sum of IS1 and IDSS2 (this does not include secondary losses)
measure the PRIMARY BYPASS pin current at 6.2 V.
C. Since the output MOSFET is switching, it is difficult to isolate the switching current from the
supply current at the Drain. An alternative is to D. The PRIMARY BYPASS pin is not intended
for sourcing supply current to external circuitry. E. To ensure correct current limit it is
recommended that nominal 0.1 mF/1 mF/10 mF capacitors are used. In addition, the BPP
capacitor value
tolerance should be equal or better than indicated below across the ambient temperature range of
the target application. The minimum and maximum capacitor values are guaranteed by
characterization. Nominal PRIMARY BYPASS Pin Capacitor Value 0.1 mF 1 mF 10 mF
Tolerance Relative to Nominal Capacitor Value Minimum -60% -50% -50% Maximum +100%
+100% N/A
F. This parameter is derived from the change in current limit measured at 1X and 4X of the di/dt
shown in the ILIMIT specification. G. Auto-restart on-time has same temperature characteristics
as the oscillator (inversely proportional to frequency). H. IDSS1 is the worst-case OFF-state
leakage specification at 80% of BVDSS and the maximum operating junction temperature.
IDSS2 is a typical
specification under worst-case application conditions (rectified 230 VAC) for no-load
consumption calculations.
I. Breakdown voltage may be checked against minimum BVDSS specification by ramping Drain
voltage up to but not exceeding minimum BVDSS. J. For reference only. This is the total range
of current limit threshold which corrects for variations in the current sense bond wire. Both of K.
Measured at the VOUT pin of the device. At the end of the cable under-load, the apparent autorestart threshold will be lower.
