The ULP Series of miniature high voltage power supplies offers orders of magnitude reduction in power consumption,
enabling designers to reduce battery size and weight in portable, scientific instruments.
Standard output voltages are available from 500 V through 5000 V, with power consumption at full output voltage, no load,
running typically just 2 mW.
The output voltage is regulated and programmable, and is capable of delivering up to 4 W of power on demand at a typical
conversion efficiency of >85%. Its proprietary packaging results in a lightweight package weighing 2.0 ounces (typical),
and features a height of only one half inch. Perfect for “green” designs, these power supplies also feature a shutdown pin
which drops current consumption to less than 5 µA. Standard input voltage range is 5.4 to 7.4 V.
Designed for portable, battery powered equipment, the ULP series is offered with a standard operating temperature range
of -20°C to +70°C, and an optional extended operating temperature of -55°C to +85°C.

Ripple
Frequency
[kHz]
Due to the pulse-burst-mode topology used to achieve ultra-low power consumption, the output variation is larger than the other typical EMCO designs.
The actual ripple amplitude and frequency depend on both the load current
and the output voltage setting. The adjacent table shows the ripple characteristics of a typical ULP10P unit.
If this level of ripple is unacceptable for the application, it can be greatly
attenuated with a simple output filter. If the load current is very light, a
blocking diode and a capacitor can be used to greatly reduce the output variation. For heavier load currents, the internal resistance becomes a smaller percent of the load. The diode can be replaced with a resistor to form a conventional RC filter.
To prevent output overshoot, if desired, limit the programming input ramp
to 600 mV/s.
