Description

The ACE722E is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up

to 2A of output current. The devices operate from an input voltage range of 2.6V to 5.5V and provide

output voltages from 0.6V to VIN, making the ACE722E ideal for low voltage power conversions. Running

at a fixed frequency of 3MHz allows the use of small inductance value and low DCR inductors, thereby

achieving higher efficiencies. Other external components, such as ceramic input and output caps, can

also be small due to higher switching frequency, while maintaining exceptional low noise output voltages.

Built-in EMI reduction circuitry makes this converter ideal power supply for RF applications. Internal

soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves

design reliability.

ACE722E is housed in a tiny SOT23-5/ DFN2x2-8L package
