PL3378 Datasheet (PMicro) - Accurate CC/CV Primary Side PWM Power Switch

PL3378, Accurate CC/CV Primary Side PWM Power Switch

PL3378 is a high efficiency Primary Side Regulator and highly integrated PWM Power Switch for AC/DC power supply applications.

It simplifies conventional CC/CV charger/adaptor designs by eliminating the opto-coupler and secondary control circuitry.

Constant output voltage and current regulation is r
