Product Overview

170W SMPS with digitally controlled PFC and resonant LLC stage based on the STNRG388A. This evaluation board is intended for evaluating the STNRG388A digital controller in off-line power conversion applications such as digital industrial power supplies. The solution implements a PFC stage followed by a resonant LLC stage supporting up to 170W. The application supports multiple output rails : high power 24V (6A) channel for the main application, 1 auxiliary 12V (2 A) for the controller and an always-on 5V (2A) standby. The STNRG388A power conversion dedicated peripherals (SMEDs) offer the flexibility to drive the PFC in transition mode (DCM-CCM boundary) while the resonant LLC is controlled with timeshiftcontrol (TSC). In parallel to managing the two conversion stages, STNRG388A guarantees all the protections required by the application as well as implementing the advanced anti capacitive protection.
  • Enhanced constant ON time PFC
  • Timeshift controlled LLC
  • Efficiency is more than 91% at full load
  • Standby consumption of less than 150mW with 50mW secondary side load
  • Input voltage range from 90 to 264Vdc
  • Modular power and control board
