ST6850
DESCRIPTION The ST6850 is the current mode PWM controller with green-mode power-saving operation which can meet the low standby-power needs for low power SMPS. This greenmode function enables the power supply to easily meet even the strictest power conservation requirements. The small package provides the high efficiency / low cost solution for SMPS power applications. ST6850 is processed by BiCMOS fabrication, that enables reducing the start-up current and the operating current. ST6850 is available by SOT-23-6L / DIP-8P packages.
