Introduces the features and applications of L6562A switch power supply controller

This document provides preliminary information on a new product that is currently under development or evaluation. The details of the product are subject to change. The product is a transition-mode power factor correction (PFC) controller with features such as a proprietary multiplier design for minimum total harmonic distortion, adjustable output overvoltage protection, ultra-low startup current, low quiescent current, and more. It is suitable for applications such as PFC pre-regulators for IEC61000-3-2 compliant SMPS, high-end AC-DC adapter/charger up to 400W, electronic ballast, entry-level server, and web server.

L6562A is a transition-mode PFC controller from ST with the following features: proprietary multiplier design for minimum thd, very accurate adjustable output overvoltage protection, ultra-low (30µA) start-up current, low (2.5mA) quiescent current, digital leading-edge blanking on current sense, disable function on E/A input, 1.4% (@ TJ = 25 °C) internal reference voltage, -600/+800mA totem pole gate driver with active pull-down during UVLO and voltage clamp.
