The EVLSTNRG-1KW is a 1 kW SMPS evaluation board designed for evaluating the STNRG388A digital controller in offline power conversion applications. It uses a 3-phase interleaved DC/DC architecture based on a half bridge SAB (Single Active Bridge) topology, supporting more than 1000 W of power.
Key electrical specifications include an input voltage range of 350 to 420 V dc, a regulated output of 133 V and 7.5 A, and a maximum output current of 2.5 A per phase. The board achieves more than 94% efficiency from 10% to full load, with a peak efficiency of 96.5% at full load. Stand-by consumption is 425 mW, and output regulation is constant current/constant voltage (CC/CV).
The interleaved topology balances power across three parallel stages, enabling high efficiency across the entire load range by activating one, two, or three stages as needed. The STNRG388A's dedicated power conversion peripherals (SMEDs) ensure correct phase realignment during stage activation and deactivation. The board is supplied as a set of board(s) and is intended for applications such as EV battery chargers, UPS, and industrial power supplies.
