NCP1910B100DWR2G

AC DC Converters, Offline Switchers Overview

The NCP1910B100DWR2G is a high-performance combo controller designed for ATX power supplies, housed in an SO-24WB package. It integrates a 100 kHz continuous conduction mode (CCM) power factor controller and an LLC controller with a high-voltage driver. The device supports over 85 types of offline power supplies. Key features include adjustable frequency foldback for light-load efficiency, dedicated pins for primary-to-secondary side handshaking compliant with ATX specifications, and an OVP input for redundancy against feedback network drift. A fast fault input enables immediate reaction to overcurrent conditions by triggering an auto-recovery soft-start sequence.
