Wide range single output demonstration board based on the VIPER26HN

The STEVAL-ISA111V1 demonstration board is a 12 V, 1 A power supply set in non-isolated flyback topology using the VIPER26HN, the new offline high voltage converter by STMicroelectronics.

The features include an 800 V avalanche rugged power section, PWM operation at 115 kHz with frequency jittering for lower EMI, current limiting with adjustable set point, onboard soft-start, a safe auto-restart after a fault condition and a low standby power. The protections include thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.

Key Features

  • Universal input mains range:
    • input voltage 90 - 264 VAC
    • frequency 45 - 65 Hz
  • Single-output voltage: 12 V at 1 A continuous operation
  • Standby mains consumption: < 30 mW at 230 VAC
  • Average efficiency: > 80%
  • Fully protected against faults (overload, feedback disconnection and overheating)
  • EMI: according to EN55022-Class-B
  • RoHS compliant
