Description
The NCL30488 is a high PF Single stage Constant Current and Constant Voltage PSR PWM controller for Flyback/ Buck-Boost/ Sepic/ Boost. This controller operates in a QR mode to provide high efficiency. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side. The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design.
Features
- Integrated 700 V HV Startup
- Precise current regulation accuracy (<±2% typical)
- Precise voltage regulation accuracy (<±1% typical)
- PF(>0.95)/THD(<10%)
- Quasi-resonant control
- Optional PSR/SSR mode
- Protections - BO/ Line OVP/ VCC OVP - LED Open/ short protection - Winding / Diode short protection - TSD
Typical applications
- Non-Dimmable LED Driver
