G5302 - Step-Down DC-DC Converter

Datasheet Summary

Description

The G5302 is a Synchronous Buck Converter, steps down an input voltage in the range from 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V.

Output voltage is set by using VCON analog input to control power levels and efficiency of the RF PA.
