Overview

Description
The SG6961 is a boundary mode PFC controller IC designed for controlling PFC pre-regulators. It provides controlled on-time to regulate output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable for safe operation during AC brownouts. An innovative multi-vector error amplifier provides rapid transient response and precise output voltage clamping. A built-in circuit disables the controller if the output feedback loop is opened. The startup current is below 20μA, and the operating current is under 4.5mA. The supply voltage can be up to 20V, maximizing application flexibility.

Features
Boundary mode PFC controller
Low input current THD
Controlled on-time PWM
Zero-current detection
Cycle-by-cycle current limiting
Leading-edge blanking instead of RC filtering
Low startup current: 10µA (typical)
Low operating current: 4.5mA (typical)
Feedback open-loop protection
Programmable maximum on-time
Output over-voltage clamping protection
Clamped gate output voltage 16.5V

Applications
Electric lamp ballasts
AC-DC switching mode power converters
Open-frame power supplies and power adapters
