STMicroelectronics VIPer26K High Voltage Converter

STMicroelectronics VIPer26K High Voltage Converter is a high voltage converter that smartly integrates a 1050V avalanche-rugged power section with a PWM current mode control. The 1050V-BV power MOSFET allows the user to extend the input voltage range and reduce the size of the DRAIN snubber circuit. The VIPer26K meets the most stringent energy-saving standards as it has very low consumption and operates in burst mode under a light load. The integrated HV startup, sense-FET, error amplifier, and oscillator with jitter allow a complete application to be designed with the minimum number of components. The VIPer26K supports the most common SMPS topologies such as isolated flyback with an optocoupler, primary-side regulation, non-isolated flyback with resistive feedback, buck, and buck-boost.

Features

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

Applications

  • SMPS for energy metering
  • Auxiliary power supplies for 3-phase input industrial systems
  • LED lighting
  • Air conditioning
