Infineon Technologies ICL8810 | Demoboard REF_ICL8810_LED_42W_PSR
42 W PFC-PSR-flyback reference design with ICL8810
Overview
| Topology | Flyback Converter |
| Input voltage | 100-264 V |
| Switching frequency | 52 kHz |
| Output 1 | 54 V / 0.75 A |
| IC revision | 1.1 |
Description
Constant voltage primary-side regulated (PSR) topology is becoming more popular because of the lower cost compared with secondary-side regulated (SSR) topology. Components such as an optocoupler, a voltage reference and an error amplifier are no longer needed. It has excellent accuracy of ±3.5 percent in the range of 100 to 10 percent of the output power. Constant voltage PSR topology is the best solution for on/off LED drivers or LED drivers with minimum dimming levels down to 5 percent.
Features
- Optimized as secondary-side-regulated (SSR) constant voltage (CV) output flyback controller, also well suited for PSR
- Power factor (PF) > 0.9 and THD < 10% across a wide load range (AC input up to 277Vrms)
- Integrated burst mode enables a very low stand-by power < 100mW
- Critical conduction mode and quasi-resonant mode with smart valley hopping
- External start-up circuit control signal
- Comprehensive set of protections (OVP, OCP, etc.)
Typical applications
- monitor up to 125W
- LED lighting, Smart lighting
- flat TV, all-in-one PC
- Adapter & charger, LED driver and luminaires up to 125W.
