AC-DC Active Clamp  
Flyback PWM IC  
NCP1568  
The NCP1568 is a highly integrated acdc PWM controller  
designed to implement an active clamp flyback topology. NCP1568  
employs a proprietary variable frequency algorithm to enable zero  
voltage switching (ZVS) of SuperJunction 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. The Active Clamp Flyback (ACF)  
operation simplifies EMI filter design to avoid interference with other  
sensitive circuits in the system. The NCP1568 features a HV startup  
circuit, a strong low side driver, and a 5 V logic level driver for the  
active clamp FET. The NCP1568 is suitable for a variety of  
applications including acdc adapters, industrial, telecom, lighting,  
and other applications where power density is an important  
requirement.  
The NCP1568 also features multimode operation and transitions  
from ACF mode to Discontinuous Conduction Mode (DCM) to meet  
regulatory requirements from around the world. The NCP1568 further  
implements skip in standby mode, resulting in excellent standby  
power. The combination of flexible control scheme and user  
programmable features allow the use of NCP1568 with  
SuperJunction MOSFETs (Si) and Gallium Nitride (GaN) FETs.
