HV FLT RT DTH FB CS 1 16 NCP1568 4 13 5 12 6 11 7 10 8 9 SW ATH ADRV VCC LDRV GND Figure 2. Pinout Table 1. PIN FUNCTIONAL DESCRIPTION Pin Out Controller Option Name Function 1 HV Input to the HV startup circuit. Information derived from HV pin is also used for BO detection, AC line presence detection and over power protection 2,3,14.
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 ac−dc 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 p.
