DESCRIPTION

IN3251G is a highly integrated current mode

PWM controller, optimized for high performance,

low standby power consumption and wide output

voltage range charger and adapter solutions. The

circuit is as well compatible with cost effective

offline flyback converter applications covering a

wide output range.20W氮化镓过认证方案

At full loading, the IC operates in fixed

frequency mode. When the loading goes low, it

operates in Green mode with valley switching for

high power conversion efficiency can be achieved

in the whole loading range.
