NCP1568G04DBR2G Description

Short technical summary and product information.

The NCP1568G04DBR2G is a highly integrated AC-DC PWM controller designed for active clamp flyback topologies. It utilizes a proprietary variable frequency algorithm to achieve zero voltage switching (ZVS) for Super-Junction or GaN FETs across various line, load, and output conditions. This ZVS capability enhances power density by allowing higher operating frequencies while maintaining high efficiency.

 

The controller supports multimode operation, transitioning from Active Clamp Flyback (ACF) mode to Discontinuous Conduction Mode (DCM) to meet regulatory requirements. It also features skip mode for excellent standby power, with standby power consumption less than 30 mW. The device is suitable for applications requiring high power density, such as AC-DC adapters, industrial equipment, telecom systems, and lighting.

 

Key features include a 700V startup circuit, AC line brownout detection, and integrated adaptive dead-time control for both main and active clamp FETs. It employs peak current-mode control with inbuilt slope compensation. The flexible control scheme and programmability allow configuration with external Silicon or GaN FETs. The operating temperature range is -40°C to 125°C (TJ), and it is available in a 16-TSSOP surface mount package.
