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.
The L6562A is a current‑mode PFC controller that operates in Transition Mode. It offers low THD, ultra‑low start‑up current and a built‑in disable function for energy‑saving applications.
The document provides detailed pin descriptions, maximum ratings, thermal data, electrical characteristics, and example applications, making it a complete reference for designers integrating the device into SMPS solutions.
