ACE710C Datasheet, PDF (1/8 Pages) ACE Technology Co., LTD. – 1A Synchronous PWM Boost converter

ACE710C
1A Synchronous PWM Boost converter
Description
The ACE710C is a step-up converter that provides a boosted output voltage from a low voltage source.
Because of its proprietary design, it starts up at a very low input voltage down to 0.9V, and only consumes
15uA at standby, making it an ideal choice for single cell alkaline/NiMH battery operations.
A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile
inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing
external parts count.
ACE710C is available in SOT23-5 Package.
