NCP1654BD65R2G

NCP1654BD65R2G IC 54B65 is a controller for continuous conduction mode (CCM) power factor correction step−up pre−converters. It uses a fixed frequency mode and depends on the instantaneous coil current to control the power switch on-time (PWM). The circuit is packaged in SO8, which minimizes the number of external components and greatly simplifies PFC implementation. It also integrates high security protection functions, making NCP1654BD65R2G a powerful and compact PFC-level driver.

Features:

1. Very low starting current (<75 A)

2. Very low shutdown current (< 400 A)

3. Undervoltage detection for open loop detection or shutdown

4. Accurate overcurrent limit

5. Surge current detection
