SSOP10 Description
Features 800 V avalanche-rugged power MOSFET
allowing ultra wide VAC input range to be
covered Embedded HV startup and sense-FET Current mode PWM controller Drain current limit protection
– 480 mA (VIPER114)
– 590 mA (VIPER115) Wide supply voltage range: 4.5 V to 30 V Minimized system input power consumption:
– Less than 10 mW at 230 VAC in no-load
condition
– Less than 400 mW at 230 VAC with 250
mW load The device is a high voltage converter smartly
integrating an 800 V avalanche-rugged power
MOSFET with PWM current mode control. The
power MOSFET with 800 V breakdown voltage
allows the extended input voltage range to be
applied, as well as the size of the DRAIN snubber
circuit to be reduced. This IC meets the most
stringent energy-saving standards as it has very
low consumption and operates in pulse frequency
modulation under light load. The design of …
