Description
WISAIR502 is a highly integrated, high-performance current mode PWM controller chip designed for power adapters and small to medium-power switch power supplies. It features a pulse mode (Burst Mode) function that reduces standby power consumption to meet environmental standards. With a very low starting current and operating current, WISAIR502 offers improved power conversion efficiency and reduced power consumption. This chip also includes built-in features such as synchronized slope compensation, by-cycle current limit protection, and VDD over-voltage clamping protection.
