ACE722G
5V 2.0A, 1.3MHz Synchronous Buck Converter
Description
The ACE722G is a high-efficiency, DC-to-DC step-down switching regulators, capable of delivering
up to 2A of output current. The device operates from an input voltage range of 2.5V to 6.0V and provides
an output voltage from 0.6V to VIN, making the ACE722G ideal for low voltage power conversions.
Running at a fixed frequency of 1.3MHz 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 ACE722G
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. The
ACE722G is available in a SOT23-6 Package
