产品概述
描述
The 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 24 V (6 A) channel for the main application, 1 auxiliary 12 V (2 A) for the controller and an always-on 5 V (2 A) 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 timeshift control (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.
Thanks to the digital core of STNRG388A, it is also possible to monitor, control and debug the EVLSTNRG-170W board via a convenient HyperTerminal control.
