STEVAL-ISA113V1:Wide range single-output demonstration board based on the VIPER06HS

The STEVAL-ISA113V1 demonstration board is a 12 V-0.35 A power supply set in non-isolated flyback topology using the new VIPER06HS offline high-voltage converter by STMicroelectronics.

The features of the device 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 protection features available include a thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.

Key Features

  • Universal input mains range:
    • input voltage 90 - 265 VAC
    • frequency 45 - 65 Hz
  • Single-output voltage: 12 V at 0.35 A continuous operation
  • Standby mains consumption: < 30 mW at 230 VAC
  • Average efficiency: > 74%
  • Fully protected against faults (overload, feedback disconnection and overheating)
  • EMI: according to EN55022-Class-B
  • RoHS compliant
