Product Overview
NCP1345Q00D1R2G 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.
- 150V wide range Vcc architecture
- Auto-tuning skip
- Frequency foldback-disabled
- SR spike reduction circuitry (adaptive gate drive)
- Improved frequency jittering
- 350KHz high frequency QR
- Internal 700V start-up w X2 discharge
- Improved light load efficiency
- Improve standby power
- Enable smaller magnetic designs
