ON Semiconductor NCP1345 is a highly integrated quasi-resonant flyback controller suitable for designing high-performance offline USB-PD and USB Type-C power converters. The included two-pin VCC architecture allows direct connection to the auxiliary winding to simplify VCC management, reduce part count and improve performance.

The NCP1345 also features an accurate primary-side based output current limit circuit to ensure constant output current limit independent of programmed output voltage or nameplate output power.

Features of ON Semiconductor NCP1345:

1. 150V wide range Vcc architecture

2. Automatic adjustment skip

3. Fast frequency foldback

4. Constant output current limit

5. SR spike reduction circuit (adaptive gate drive)

6. Improved frequency jitter

7. 350KHz high frequency QR

8. Internal 700V starts wX2 discharge

Benefits of ON Semiconductor NCP1345;

1. Adjust skip entries according to VOUT

2. Improve light load efficiency

3. Meet the LPS (Limited Power Supply) requirements in PPS

4. Use SR FETs with lower voltage ratings

5. Softer EMI signature

6. Achieve a smaller magnetic design

7. Improve standby power

Application products of ON Semiconductor NCP1345:

1. Phone, tablet and laptop chargers

2. Aftermarket USB PD multi-port charger

3. A wall socket that supports USB C
