EVLSTNRG-170W, Evaluation Board based on the STNRG388A 170-W SMPS with digitally controlled PFC and resonant LLC stage
EVLSTNRG-170W, 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 170 W. The application supports multiple output rails: a high power 24V (6A) channel for the main application, 1 auxiliary 12V (2A) for the controller and an always-on 5V (2A) standby. The STNRG388A power conversion dedicated peripherals offer the flexibility to drive the PFC in transition mode (DCM-CCM boundary) while the resonant LLC is controlled with time shift control
