SG6858 : This highly integrated PWM controller provides several special enhancements designed to meet the low standby-power needs of low-power SMPS. To minimize standby power consumption, the proprietary greenmode function provides off-time modulation to linearly decrease the switching frequency under light-load conditions. This green-mode function enables the power supply to meet even the strictest power conservation requirements. The BiCMOS fabrication process enables reducing the startup current to 10µA and the operating current to 2.5mA. To further improve power conservation, a large startup resistance can be used. Built-in synchronized slope compensation ensures the stability of peakcurrent-mode.
