Power chip

Product Overview The NCP1568 is a highly integrated AC-DC PWM controller for implementing an Active Clamp Flyback topology. The NCP1568 uses a proprietary frequency conversion algorithm to achieve zero-voltage switching (ZVS) of MOSFETs under various line and load conditions. The ZVS function enables high frequency operation, increasing the power density of the power converter while achieving high energy efficiency. Integrates a high-voltage start-up circuit, a powerful low-side driver, and a 5-V logic-level driver for active-clamp FETs, including SJ FETs and GaN FETs. The NCP1568 is suitable for a variety of applications including AC-DC adapters, industrial, telecom, lighting and other applications with important power density requirements.
