Continuously improving technology has led to a continuous decline in the total power consumption of PC central processing units (CPUs). However, with the rapid increase in GPU power consumption, the overall power consumption of PCs has brought new challenges to power supplies. The market for PC power supplies requires smaller size or higher cost performance. Inmark uses two solutions, planar MOS and SJ COOL MOS, which can meet the requirements of faster switching speed, lower conduction loss, and extremely low gate charge (Qg), thereby reducing the power loss of the device and improving system efficiency. It also provides a variety of options with better EMI. At the same time, we recommend planar Schottky and deep trench low VF Schottky in terms of Schottky, which can meet the requirements of higher efficiency and lower cost.
