Overview
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 due to bleeding resistors is eliminated.
To further reduce power consumption, SG6742 is manufactured using the BiCMOS process, which allows an operating current of 4mA.
SG6742 integrates a frequency a h...
