STMicroelectronics L6562AD

Description
The STL6562A is a transition-mode PFC controller designed for power factor correction (PFC) pre-regulators in switch-mode power supplies (SMPS). It features a proprietary multiplier design for minimum total harmonic distortion (THD) and a very accurate adjustable output overvoltage protection. The device has an ultra-low (30μA) start-up current and a low (2.5mA) quiescent current. It also includes digital leading-edge blanking on current sense, a disable function on E/A input, and a 1% (T = 25 °C) internal reference voltage. The STL6562A has a -600/ 800mA totem pole gate driver with active pull-down during UVLO and voltage clamp. It is available in DIP-8 and SO-8 packages.
