STMicroelectronics EVLSTCH03-36W-SR Demonstration Board
STMicroelectronics EVLSTCH03-36W-SR Demonstration Board is a 36W wide-range mains USB charger with selectable output voltage (5V-9V-12V at 3A output current). The board is based on the STCH03L and SRK1000B. The power circuit is a quasi-resonant (QR) flyback converter, with peak current mode control. The circuit operates with secondary side constant voltage (CV) regulation through an optocoupler. STMicroelectronics EVLSTCH03-36W-SR Demonstration Board can provide constant output current (CC) regulation using primary sensing feedback.
