GMT致新 G2225RV1U TQFN4x4-28 代理商主推
General Description
The G2225 provide a complete power supply solution
for wearable / sports-cam & IP-CAM application. It
contains four dc/dc converters, one power switch and
one low quiescent current 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. All channels DC/DC
converters operate at selectable frequency of
1.5/3.0MHz to optimize size, cost, and efficiency. All
Synchronous converters operate at pulse skipping
mode at light load.
The G2225 is available in TQFN4x4-28 package.
