L6563STR ST Power Factor Correction (PFC)

The L6563STR is a transition-mode Power Factor Correction (PFC) controller from STMicroelectronics in SO-14 surface-mount package, operating from 10.3V to 22.5V supply with advanced features including tracking boost function and 800mA totem pole gate driver . For selection, verify low start-up current, operating quiescent current, adjustable frequency operation, voltage feed-forward for near-unity power factor, THD optimizer for low distortion, tracking boost function for output voltage proportional to mains voltage, and operating temperature from -40°C to +150°C. Features include overvoltage protection, feedback disconnect protection, disable function for standby operation, precise adjustable output voltage, burst-mode operation at zero load, and fast output voltage discharge during UVLO. Ideal for power supplies with active PFC (>65W) requiring EN61000-3-2 compliance, AC-DC adapters, electronic ballasts, LED drivers, and flat-screen TV power supplies with tracking boost functionality.
