PL3395A Secondary Feedback PWM Power Switch Datasheet
■PL3395A is a high performance and low cost current mode PWM controller which provides several special enhancements designed to meet low standby power requirements. The start-up current is very low, typically 5μA, and the operation current is also low. The “No Audio Noise Green Mode” function is integrated to improve the efficiency at light or no load conditions. This green-mode function enables the power supply to meet even the strictest power conservation requirements easily.
■The built-in slope compensation ensures the stability of peak current mode control. The integrated frequency jitter function helps to reduce EMI emission of a power supply with minimum line filters.
■PL3395A also offers rich protection features including Cycle-by-Cycle peak current limiting, UVLO, VDD over voltage, load OVP, OLP, and OTP.
