STMicroelectronics L6562 Manuals

This document describes the features and characteristics of the L6562 PFC controller, including the use of BCD technology, transition-mode control of PFC pre-regulators, proprietary multiplier design for minimum THD of AC input current, very precise adjustable output overvoltage protection, ultra-low startup current and quiescent current, extended IC supply voltage range, on-chip filter on current sense, disable function, 1% internal reference voltage, -600/+800mA totem pole gate driver with UVLO pull-down and voltage clamp, and DIP-8/SO-8 packages. This product is suitable for PFC pre-regulators in IEC61000-3-2 compliant SMPS (TV, desktop PC, monitor) up to 300W, high-end AC-DC adapter/charger, and entry level server & web server applications.

The L6562 is a current-mode PFC controller operating in Transition Mode (TM). Pin-to-pin compatible with the predecessor L6561, it offers improved performance.

The document introduces the features and characteristics of L6562, including BCD technology, transition mode control, proprietary multiplier design, adjustable output overvoltage protection, ultra-low startup current, and low quiescent current.

L6562 is a transition-mode PFC controller from Texas Instruments. The device is manufactured in BCD technology and features low startup current, low quiescent current, extended IC supply voltage range, on-chip filter on current sense, disable function, 1% (@ Tj = 25°C) internal reference voltage, -600/+800mA totem pole gate driver with UVLO pull-down and voltage clamp. The device is used in PFC pre-regulators for IEC61000-3-2 compliant SMPS (TV, desktop PC, monitor) and other devices.
