PL3379C Accurate CC/CV Primary Side PWM Power Switch Datasheet
■PL3379C 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.
■Multi-mode operations are utilized to achieve low standby power, high efficiency and audio & noise free. PL3379C 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.
■PL3379C also offers rich protection features including Cycle-by-Cycle peak current limiting, UVLO, OTP, load OVP, and VDD over voltage.
