SG6961 Critical Conduction Mode PFC Controller Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ Description 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 The SG6961 is an 8-pin boundary mode PFC controller IC intended for controlling PFC pre-regulators. The SG6961 provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable to ensure safe operation during AC brownouts. An innovative multi-vector error amplifier is built in to provide 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 lower than 20µA and the operating current is under 4.5mA. The supply voltage can be up to 20V, maximizing application flexibility.
