ONSEMI NCP1568G03DBR2G Active Clamp PWM Controller
The NCP1568 is a high-performance active clamp flyback PWM controller designed for high density power supplies, including adapters and industrial applications. It employs a proprietary variable frequency algorithm enabling zero voltage switching (ZVS) of super-junction and GaN FETs, enhancing efficiency and power density. Features include multimode operation transitioning between active clamp and DCM modes, integrated brownout detection, a 700 V startup circuit, and programmable oscillator frequency from 100 kHz to 1 MHz. The controller simplifies EMI filtering, provides excellent standby power below 30 mW, and supports advanced safety protections, making it ideal for telecom, lighting, and industrial power systems.
