Infineon Technologies REF_LLC_BUCK_4CH_320W Reference Design

Infineon Technologies REF_LLC_BUCK_4CH_320W Reference Design demonstrates a 320W high-power LED driver circuit with four Constant Current (CC) output channels. This Reference Design is based on ILD8150 LED Drivers and the ICL5102 High-Performance PFC Resonant Controller. The Reference Design uses an ICL5102 320W Reference Board as the pre-stage of the LED driver circuit, with CV output. Four ILD8150 100W Reference Boards are the end-stage with CC output for direct connection to LED modules.

Features

ICL5102 320W Reference Board
- Dual-stage half-bridge (LLC) and separated power factor correction (PFC) with high-precision secondary side-controlled CV output
- Excellent output voltage accuracy of typically ±4% across universal input voltage range (90V to 305V) and wide output current range (from 0A to 4.35A)
- High PF (greater than 0.9) across universal input voltage range (90V_AC to 305V_AC) and down to 50% of nominal load
- Low input current total harmonic distortion (iTHD less than 15%) across universal input voltage range (90V to 305V) and down to 30% of nominal load

ILD8150 100W Reference Board
- Wide input voltage range from 8V to 80V with a maximum 1.5A output current
- Hybrid output dimming with PWM dimming frequency up to 20kHz
- Shut-down mode with low power consumption for dim-to-off
