Power Supply Circuit Design of Domestic Power Supply Chip for 5G Small Cell BBU
In this paper,a power supply design scheme of 5G small cell BBU based on domestic SGMICRO SGM61163XTRI14G synchronous buck DC-DC power supply chip is proposed.By leveraging the chip's high efficiency,wide output voltage range(0.9V-5V)and large load capacity(6A),this scheme achieves a power supply with high cost-effectiveness and stable supply chain.This design not only solves the problems of high price and long supply cycle of imported chips,but also improves the performance of power supply module by optimizing the PCB layout and heat dissipation scheme,thus providing a reliable guarantee for the stable operation of 5G small cells.
