其次，采用了一种基于单片机AT89C51的智能稳压开关电源的设计方案，

Secondly, a design scheme of intelligent stabilized switching power supply based on the single-chip AT89C51 is adopted. By using a single-chip microcomputer to control digital conversion to analog conversion, it combines the equalization and filtering induced voltage stabilization part, the DAC0832 conversion circuit and the LCD1602 display part to realize one A power supply ranging from 0~15V with 0.5V step-by-step adjustable regulated power supply. This system realizes the step-by-step regulation of the regulated power supply, over-current alarm and real-time display, and makes up for some shortcomings of the integrated circuit LM317 power supply.

Secondly, a design scheme based on the microcontroller AT89C51 intelligent regulator switching power supply is adopted, which combines equalization and filter sensing voltage stabilization, DAC0832 conversion circuit and LCD1602 display part of the common realization of a power supply from 0 to 15V at 0.5V per step step adjustable regulator power supply, the system to achieve step-by-step regulation of regulated power supply, overcurrent alarm and real-time display, Make up for some of the shortcomings in the LM317 power supply of the integrated circuit.
