Description

The ACE721C is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering up to

1.2A of output current. The device operates from an input voltage range of 2.6V to 7.0V and provides an

output voltage from 0.6V to VIN, making the ACE721C ideal for low voltage power conversions. Running

at a fixed frequency of 1.5MHz allows the use of small external components, such as ceramic input and

output caps, as well as small inductors, while still providing low output ripples. This low noise output along

with its excellent efficiency achieved by the internal synchronous rectifier, making ACE721C an ideal

green replacement for large power consuming linear regulators. Internal soft-start control circuitry reduces

inrush current. Short-circuit and thermal-overload protection improves design reliability.
