12 V/12 W wide range non-isolated flyback based on the VIPER26LN

The STEVAL-ISA110V1 demonstration board is a 12 V-1 A power supply set in non-isolated flyback topology using the VIPER26LN, a new offline high-voltage converter by STMicroelectronics.

The features of the device include an 800 V avalanche-rugged power section, PWM operation at 60 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 low standby power.

Protection features 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 @ 1 A continuous operation
  • Standby mains consumption: < 30 mW @ 265 VAC
  • Average efficiency: > 85%
  • Fully protected against faults (overload, feedback disconnection and overheating)
  • EMI: according to EN55022-Class-B
