PL3378 Accurate CC/CV Primary Side PWM Power Switch Product Description 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. Multi-mode operations are utilized to achieve low standby power, high efficiency and audio & noise free. PL3378 operates in PFM mode at large load condition, with the load becomes medium or light, the chip operates in Green mode to achieve high efficiency.
