EMQ8932 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP Portable Devices General Description The EMQ8932 is a high efficiency, 4-channel power management IC for portable devices application. It integrates a plete linear charger for single cell lithium-ion battery, a linear regulator and two high efficiency step-down DC/DC converters. The linear charger (CH1) operates from 4.25V to 5.5V input voltage and up to 1A charging capability. It is thermal regulated and specifically designed to work within USB power specifications. The linear regulator (CH2) Features ultra-high power supply rejection ratio (75dB at 1kHz), low output voltage noise (30µV), low dropout voltage (270mV), low quiescent current (110µA) and fast transient response....
