Product Description
PL3368A is a high efficiency Primary Side Regulator andhighly integrated PWM Power Switch for AC/DC powersupply applications. It simplifies conventional CC/CVcharger/adaptor designs by eliminating the opto-couplerand secondary control circuitry. Constant output voltageand current regulation is realized as shown in the Fig.1below.Multi-mode operations are utilized to achieve low standbypower, high efficiency and audio & noise free.
PL3368Aoperates in PFM mode at large load condition, with theload becomes medium or light, the chip operates in Greenmode to achieve high efficiency.PL3368A also offers rich protection features includingCycle-by-Cycle peak current limiting, UVLO, OTP, loadOVP, and VDD over voltage.
