The REF_ICL8810_LED_42W_PSR is a 42W reference design featuring Infineon’s high power factor flyback controllerICL8810. The board is a constant voltage (CV) primary-side regulated (PSR) system and is intended to be used with a constant current (CC) converter forLED lighting applications. Compared to SSR, PSR shows significant cost advantages. Components, such as an optocoupler, a voltage reference, and an error amplifier are no longer needed. Thus, REF_ICL8810_LED_42W_PSR is the perfect, cost-optimized solution for on/off LED drivers or LED drivers with minimum dimming levels down to 5 percent. The board has excellent accuracy of ±3.5% in the range of 10% to 100% of the output power. With its benchmarking performance in power factor correction and total harmonic distortion at full-load and low-load conditions,ICL8810enables window drivers and platform designs. Furthermore, the IC combines optimum efficiency and low EMI without compromising light quality.
