DESCRIPTION

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 start-up current is lower than 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 Start-up Current (10μA Typical)

■ Low Operating Current (4.5mA Typical)

■ Feedback Open-Loop Protection

■ Programmable Maximum On-Time (MOT)

■ Output Over-Voltage Clamping Protection

■ Clamped Gate Output Voltage 16.5V

APPLICATIONS

■ Electric Lamp Ballasts

■ AC-DC Switching Mode Power Converter

■ Open-Frame Power Supplies and Power Adapters

■ Flyback Power Converters with ZCS/ZVS
