  • The device is a high performance high voltage converter that combines a 730 V rugged power MOSFET with PWM control. The device embeds high voltage startup and current sense circuitry, which helps reduce the number of components in a BoM. Frequency jittering spreads the EMI and allows the use of a smaller filter. The burst mode feature provides very low input power consumption at light loads.

    Key Features

    • 730 V avalanche rugged power MOSFET
    • PWM controller
    • 3.3 V reference voltage
    • Frequency jittering
    • 40 mW no load input power at 230 VAC
    • Short-circuit protection
    • Thermal shutdown
