Description

The EVB is a robust, isolated, QRF AC-DC converter. It uses Tagore Technology’s Superior GaN FET TP44400SG and controlled by onsemi’s controller IC NCP1342. The secondary side rectification is achieved through synchronous rectification using Low-Voltage (LV) MOSFETs and onsemi’s synchronous rectifier controller IC NCP43080DMN. The peak efficiency obtained is > 93.5 %, which leads to very low power losses within the board and helps keep the GaN FET temperature low without using any heatsink. The EVB is designed to deliver 45W (max) at 20 VDC output. In addition, there are programmable outputs of 5V, 9V, 15V for which the maximum output current is 3A. The EVB works with universal AC input voltage and frequency ranges (90V – 265V, 50/60 Hz). This EVB uses the same PCB, which is used in Tagore’s 65W EVB TP44200SG-QRF45-EVB. Most of the components BOM (except for the transformer, GaN FET, electrolytic capacitors and few other components) are also same in both the EVBs. However, for optimized design, user can develop a new PCB
