onsemi, AC-DC Converter 16-Pin, TSSOP NCP1568G03DBR2G

The ON Semiconductor NCP1568 is a highly integrated ac−dc PWM controller designed to implement an active clamp fly back topology. It employs a proprietary variable frequency algorithm to enable zero voltage switching (ZVS) of super−junction or GaN FETs across line, load, and output conditions. The ZVS feature increases power density of a power converter by increasing the operating frequency while achieving high efficiency.

Inbuilt adaptive dead−time for both main and active clamp FETs
Peak Current mode control with inbuilt slope compensation with options
DCM and light load operation
