STEVAL-ISA114V1:5 V/0.8 W wide-range 30 kHz buck converter based on the VIPer06XS

The STEVAL-ISA114V1 evaluation board describes a 5 V- 0.15 A power supply set in buck topology with the VIPer06XS, a new off-line high voltage converter by STMicroelectronics, specifically developed for non-isolated SMPS.

The features of the device include an 800 V avalanche rugged power section, PWM operation at 30 kHz with frequency jittering for lower EMI, limiting current with adjustable set point, on-board soft-start, safe auto-restart after a fault condition and low standby power consumption.

The available protection includes a thermal shutdown with hysteresis, delayed overload protection and open loop failure protection. All protection is auto-restart mode.

Key Features

  • Universal input mains range:
    • input voltage: 90 - 264 VAC
    • frequency: 45 - 65 Hz
  • Single-output voltage:
    • 5 V @ 0.16 A continuous operation
  • Fully protected against faults (overload, feedback disconnection and overheating)
  • EMI: according to EN55022-Class-B
  • RoHS compliant
