A6902D Datasheet Up to 1A step down switching regulator

Manufacturer: STMicroelectronics

General Description

The A6902D is a complete step down switching regulator with adjustable current limit.

Based on a voltage mode structure it integrates an additional current error amplifier to implement both a constant voltage and constant current control.

The current limit programming is very simple and accurate (± 5%) selecting the proper sensing resistor.
