SG6742 Datasheet (Fairchild Semiconductor) - Highly-Integrated Green-Mode PWM Controller

SG6742, Highly-Integrated Green-Mode PWM Controller

Product Specification Highly Integrated Green-Mode PWM Controller SG6742 To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency at light-load conditions.

To avoid acoustic noise problems, the minimum PWM frequency is set above 22KHz.

This green-mode function enables the power supply to meet international power conservation requirements.

With the internal high-voltage start-up circuitry, the power loss du
