G2257 - 4+1 channels PMIC

This page provides the datasheet information for the G2257, a member of the G2257-GlobalMixed 4+1 channels PMIC family.

Datasheet Summary

Description

The G2257 provide a complete power supply solution for handsets or data card.

It contains four dc/dc converters, and one LDO to power each critical blocks of the system, and is optimized for maximum battery life, featuring a low ground current when in standby mode operation.

Features

2.7V ~ 5.5V Input Voltage Operation.
95% Efficient DC/DC Converter.
Independent Enable Control.
Built-in 4-ch synchronous buck converter, and 1-ch LDO.
Bucks can be set to lower quiescent current at low load.
180o Phase Shifted architecture.
Fixed 1.5MHz switching frequency.
Built-In Short Circuit Protection (SCP), Under Voltage Protection (UVP), and cycle-by cycle current limit for DC/DC Converters.
Built-In Th.
