STMicroelectronics VIPER115LSTR Voltage-to-Frequency Converter, Voltage 1 kHz 1 %FSR, 10-Pin SSOP

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.

• 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
• Minimized system input power consumption:
• Jittered switching frequency reduces the EMI filter cost:
• Embedded E/A with 1.2 V reference
