Infineon Technologies XDPL8219 | Demoboard REF-XDPL8219-U40W
For high-power-factor flyback converter with constant voltage output
Overview
| Topology | Flyback Converter |
| Input voltage | 90-305 V |
| Output 1 | 54 V / 0.8 A |
| IC revision | 1.1 |
Description
This is a reference design of REF-XDPL8219-U40W, which is based on Infineon’s XDPL8219 high-power-factor (HPF) flyback controller and IPD80R900P7 MOSFET. Also this is a reference design for a 40 W front-stage HPF flyback converter with secondary-side regulated constant voltage output of 54 V, which can be used to supply a second-stage constant current converter for LED lighting applications.
Features
- Secondary-side regulated (SSR) constant voltage (CV) output
- Supports universal input with 90 Vrms to 305 Vrms and DC input with 127 V to 432 V
- High-power-factor (HPF) and low total harmonic distortion (iTHD), across wide AC input voltage range (120 Vrms to 277 Vrms) and wide output load range (33 percent to 100 percent of full load)
- High efficiency with quasi-resonant (QR) mode, switching in valley n (QRMn), across wide input and output load range
- No-load standby power, as low as less than 100 mW with active burst mode (ABM)
- Input overvoltage protection (OVP) and input undervoltage protection (UVP)
- Power limitation during brown-out, to better protect primary components, e.g., the flyback MOSFET, from overheating and magnetics from saturation
- Output power limitation and output UVP, under single fault condition where the second-stage constant current DC-DC converter MOSFET drain pin is shorted to the source pin
- Output and VCC OVP, under feedback open condition
- Output short protection
- VCC UVP
- Configurable parameters, e.g., brown-out power limitation slope, protection thresholds and reaction (auto restart/latch)
- Reporting of system information, e.g., input voltage, line frequency, controller temperature, input voltage loss, and error code of last triggered protection, via unidirectional UART communication
Typical applications
- LED lighting
