VIPER26K - 1050V high voltage converter

Description

The device is a high voltage converter smartly integrating a 1050 V avalanche-rugged power section, with a PWM current mode control.

The 1050 V-BV power MOSFET allows to extend input voltage range, and reduce the size of the DRAIN snubber circuit.

Features

  • 1050 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:.
  • -500 mA (VIPER265K).
  • -700 mA (VIPER267K).
  • Jittered switching frequency reduces the EMI filter cost: 60 kHz ± 4kHz.
  • Standby power < 30 mW at 230 VAC.
  • Embedded E/A with 3.3 V reference.
  • Safe auto-restart after a fault condition.
  • Hysteretic thermal shutdow.
