Infineon Technologies XDPL8220
XDPL8220 PFC+Flyback Dual-Stage MultiMode Controller 50W Reference Design with CDM10V Isolated Dimming Interface
Overview
| Topology | Flyback Converter |
| Input voltage | 90-305 V |
| Output 1 | 48 V / 1.5 A |
| IC revision | 1.1 |
Description
XDPL8220 50 W reference design is a digitally configurable LED driver which has universal input of 90 - 305 Vac, wide output load range of 16-48Vdc and isolated dimming interface (with CDM10V). Please refer next page for the main design features of this board based on XDPL8220 and CDM10V.
Features
- Dual-stage flyback with power factor correction (PFC) and high-precision primary side-controlled constant voltage (CV), constant current(CC) and limited power (LP) output.
- Excellent current accuracy of typical +/-2% across universal input voltage range (90 to 305 Vac) and wide output voltage range (from 16V-48V)
- Integrated 600 V HV cell and PFC aux winding charge pump power supply for fast startup start time under 250ms
- Multi-mode control (QR+DCM) flyback stage enables high efficiency and low dimming output
- High power factor (PF>0.9) and low input current total harmonic distortion (iTHD<15%) across universal input voltage range (90 to 305 Vac) and down to 30% load.
- Short time-to-light down to 250ms.
- Low Bill Of Materials (BOM)
- Configurable diming curve to either linear or quadratic (eye-adaptive)
- Configurable minimum dimming current from 10% to 5%
- Intelligent thermal management with adaptive temperature protection
- Active bleeder for dim-to-off function
- Output independent forward mode auxiliary power supply for controller
- Isolated dimming interface with CDM10V
Typical applications
- LED drivers
