VIPER12AS-E

Low power off-line switched-mode power supply Primary Switcher. It combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip. The internal control circuit offers the benefits like large input voltage range on the VDD pin accommodates changes in auxiliary supply voltage, automatic burst mode in low load condition and overvoltage protection in HICCUP mode. Typical applications cover off line power supplies for battery charger adapters, standby power supplies for TV or monitors, auxiliary supplies for motor control.

• Fixed 60KHz switching frequency
• 9V to 38V wide range VDD voltage
• Current mode control
• Auxiliary under voltage lockout with hysteresis
• High voltage start-up current source
• Over temperature, overcurrent and overvoltage protection with auto-restart
