SG6859A Datasheet (Fairchild Semiconductor) - Low Cost Green-Mode PWM Controller

SG6859A, Low Cost Green-Mode PWM Controller

This highly integrated PWM controller provides several enhancements designed to meet the low standby-power needs of low-power SMPS.

To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load co
