Overview
The L6561D013TR is an improved version of the L6560 standard Power Factor Corrector (PFC) from STMicroelectronics. This component is fully compatible with the standard L6560 but offers several enhanced features. It is designed to operate in transition mode and is optimized for applications requiring a wide input voltage range, from 85V to 265V, with excellent Total Harmonic Distortion (THD). The device features a reduced start-up current and a disable function on the Zero Current Detection (ZCD) pin, ensuring lower current consumption in standby mode. Realized in mixed BCD technology, the L6561D013TR is particularly suited for Electronic Lamp Ballast, AC-DC adaptors, and Switch-Mode Power Supplies (SMPS).
