DESCRIPTION

The A7122A 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 5.5V and provides an output voltage from 0.6V to VIN, making the A7122A 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 A7122A 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 A7122A is available in SOT-26 and SOT-25 packages.
