Description	Accurate CC/CV Primary Side PWM Power Switch
Datasheet	PL3378-PMicro.pdf

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 realized as shown in the Fig.1 below.

including Cycle-by-Cycle peak current limiting, UVLO, OTP, load OVP, and VDD over voltage. Key Features.
Built-in Integrated Power BJT.
Accurate Constant Current Regulation at Universal AC input.
Eliminates Opto-coupler and all Secondary CC/CV Control Circuitry.
Built-in Line Compensation for Tighter CC/CV Regulation.
Built-in Compensation for Transformer Inductance Tolerances.
Adjustable Output Cable Compensation.
Adaptive Multi-mo.
