SG6859ATZ - Brand New Fairchild Semiconductor IC Chips
-
Description
This highly integrated PWM controller, SG6859ATZ, provides several special 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 conditions. This green-mode function enables the power supply to easily meet even the strictest power conservation requirements.
