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.
The L6562A is a current‑mode PFC controller operating in Transition Mode (TM). It offers a proprietary multiplier for low THD, an accurate 1.4 % internal reference, ultra‑low start‑up current and a disable function for energy‑saving applications. The device includes a totem‑pole output stage capable of 600 mA source and 800 mA sink current, suitable for driving MOSFETs or IGBTs in high‑power SMPS.
