Product Overview

The STEVAL-ISA181V1 from STMicroelectronics is a 12V/600mA high voltage flyback converter with remote standby control using the VIPer0P. This SMPS system features an isolated flyback converter based on VIPer0P and special STM32 core logic to manage the VIPer0P for extremely low power consumption during ZPM while supplying the microcontroller and IR receiver and still maintaining relatively high overall efficiency during normal operation. The IR remote interface consists of a dedicated IR TX board and very low consumption TIA / band pass filter RX. In the ZPM idle state device shut down fully and the residual consumption from the 230VAC mains is below 5mW. The IC enters ZPM by pulling the OFF pin to SGND for more than 10ms and exits ZPM (resuming normal switching) by pulling the ON pin to SGND for more than 20µs. This function can be tested by acting on the tactile switches connected to the ON and OFF pins.
  • Smart standby architecture using Zero Power Mode (ZPM) with IR remote on/off control
  • Based on VIPer0P high voltage converter with embedded 800V avalanche rugged power MOSEFET
  • Current mode PWM controller with a set of protections for enhanced system reliability
  • Input power consumption in zero power mode lower than 8mW at 230VAC
  • Input power consumption at no load less than 30mW at 230VAC including microcontroller consumption
  • Average efficiency > 80.2% compliant with EuCoC rev. 5 - Tier 2 and EPS of DOE USA
  • Meets IEC55022 class B conducted EMI even with reduced EMI filter
  • Meets IEC61000-4-2(ESD), IEC61000-4-4 (EFT) and IEC61000-4-5 (surge)
  • Proposed power supply is set in isolated flyback topology with 12V output & 7.2W nameplate power
