EMQ9920
2 Channel Power Management IC For
Portable Devices
GENERAL DESCRIPTION
The EMQ9920 is a high efficiency, 2-channel power
management IC for battery-powered, portable
devices application. It integrates two high efficiency
step-down DC/DC converters.
The two Synchronous Buck converters (CH3, CH4)
operate from 2.5V to 5.5V input voltage, up to
600mA loading capability and regulate adjustable
output voltage from 0.6V to 5.5V. It features low
quiescent current, 1.5MHz internal frequency
operation.
The EMQ9920 is available in TQFN16 3x3 package.
It is Green compliant (RoHS and Halogen-free).
