EMQ9904 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP 4 Channel Power Management IC For Portable Devices GENERAL DESCRIPTION The EMQ9904 is a high efficiency, 4-channel power management IC for battery-powered, portable devices application. It integrates a high efficiency step-up DC/DC converter, a linear regulator and two high efficiency step-down DC/DC converters. The step-up DC/DC converter (CH1) can start up 0.9V typically with operating voltage down to 0.6V and up to 500mA loading capability. It Features with extreme low 26μA quiescent current with no load, which is the best fit for extending battery life during the standby mode. The linear regulator (CH2) Features ultra-high power supply rejection ratio (75dB at 1kHz),...
