| IC-Revision | 4 |
Beschreibung
The NCP1342PD65WGEVB showcases the NCP1342 Quasi-Resonant Flyback Controller in a USB Power Delivery (PD) application. The evaluation board delivers 60 W of power using a compact RM8 transformer. The NCP1342 is suitable for designing high-performance off-line power converters and USB PD adapters, and features Rapid Frequency Foldback (RFF) for improved efficiency over the load range. An integrated active X2 capacitor discharge feature eliminates discharge resistors which enables no-load power consumption below 40 mW.
Eigenschaften
- Minimum Peak Current Modulation for Rapid Frequency Foldback (RFF)
- QR Frequency Jittering
- Quiet-Skip Technology
- Integrated HV Startup with Brownout Protection
- Valley Switching Operaton with Valley Lockout
- Integrated X2 Capacitor Discharge Capability
- NTC Compatible Fault Pin
- High Drive Capability: -500 mA / +800 mA
- Latch input for OVP and OTP implementation
Typische Anwendungen
- Medium or High Power AC-DC Adapters, Ultra High Density AC-DC Adapters, USB PD Compliant, Notebook Adapters, Flat TV SMPS, Phone and Tablet Adapters
- Computer Power Supplies
