ACE722G
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

Note1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended Operating
Range indicates conditions for which the device is functional, but do not guarantee specific performance limits. Electrical
Characteristics state DC and AC electrical specifications under particular test conditions which guarantee specific performance
limits. This assumes that the device is within the Operating Range. Specifications are not guaranteed for parameters where no
limit is given, however, the typical value is a good indication of device performance.
