viper22a ic

The?VIPER22A?is a Popular?SMPS controller IC?form STMicroelectronics that has been extensively used in?AC to DC Converters?in offline power circuit designs. This controller IC consists of an in-built PWM controller with a power MOSFET.? The MOSFET is connected to the primary side a power transformer which when switched will produce the required output voltage based on transformer design.
