SG6741 Datasheet (Fairchild Semiconductor) - Highly-Integrated Green-Mode PWM Controller

SG6741, Highly-Integrated Green-Mode PWM Controller

Product Specification Highly-Integrated Green-Mode PWM Controller SG6741 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 due to bleeding resistors is also eliminated.

To further reduce power consumption, SG6741 is manufactured u
