Description

The ACE707C 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.

ACE707C is available in SOT-23 and SOT89-3 Package.
