The STMicroelectronics SMPS primary switcher combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip. Typical applications cover off line power supplies for battery charger adapters, standby power supplies for TV or monitors, auxiliary supplies for motor control, etc.
Current mode control
Auxiliary under voltage lockout with hysteresis
High voltage start up current source
Over temperature and overvoltage protection with auto restart
