ST6850 Datasheet, PDF (1/10 Pages) Stanson Technology – Green-Mode PWM Controller

Green-Mode PWM Controller
300mA Driving Capability
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 green-
mode 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.
