Overview

The NCP1345 is a highly integrated quasi-resonant flyback controller suitable for designing high-performance off-line USB-PD and USB Type-C power converters. The included dual-pin VCC architecture allows direct connection to the aux winding for simplified VCC management with a reduced parts count and increased performance.
The NCP1345 also features a precise, primary side based output current limiting circuit to ensure a constant output current limit regardless of programmed output voltage, or nameplate output power.
