IN3251G
20W氮化镓过认证方案， IN3251+IN1311M+LT2620APXX+EE1510 四大件1.XXRMB，60V同步，优势方案，高性价比，稳定供货
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.

IN3251G offers complete protection coverage
including cycle-by-cycle current limiting (OCP),
overload protection (OLP), over temperature
protection (OTP), output short current protection
(SCP), output and VDD over voltage protection
(OVP & VDD OVP). Excellent EMI performance is
achieved with INOCHIP proprietary frequency
shuffling technique. The tone energy at below
22KHz is minimized to avoid audio noise during
operation.， IN3251+IN1311M+LT2620APXX+EE1510 四大件1.XXRMB，60V同步，优势方案，高性价比，稳定供货
IN3251G is offered in SOP-7L package.
