Design of Low Voltage High Current DC-DC Converter Based on TPS54810

In digital signal processing system and microcomputer system, often need to high speed DSP devices and large-scale ASIC, FPGA to design and development, in these systems, the high requirement of the precision of the power module and power supply current, power supply module design will directly affect the stability of the whole system. In addition, the power supply module is usually low voltage large current of DC/DC converter, the requirement of efficiency is very high, generally over 90%. This paper introduces the FPGA based on TI company's TPS54810 power supply with low voltage large current DC/DC converter module design, this paper introduces in detail the external compensation of synchronous buck DC/DC converter power supply circuit design methods.
