For a wide range of DC input, regulated output power requirements of electrical equipment, a high-performance synchronous rectifier buck-boost power supply module is developed,which based on LT8705 of the Linear company as the control center. The power supply module is integrated with a DC-DC unit, the driving circuit unit, the loop work status of voltage and current feedback unit and the current control function unit. Meanwhile, the key circuit parameters are calculated. Experimental results show that the module power supply can achieve the desired functionality and meet the application requirements.
