AC-DC Active Clamp Flyback PWM IC NCP1568 The NCP1568 is a highly integrated ac−dc PWM controller designed to implement an active clamp flyback topology. NCP1568 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. 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.
