The TDTTP2500B066B 2.5kW bridgeless totem-pole power factor correction (PFC) evaluation board achieves very high efficiency single-phase AC-DC conversion. Using Microchip's dsPIC along with Transphorm GaN FETs in the fast-switching leg of the circuit and low-resistance MOSFETs in the slow-switching leg of the circuit results in improved performance and efficiency. The TDTTP2500B066B-KIT is for evaluation purposes only.
