The design and facture of a digital control DC regulated power supply based on single chip

The digital control technique of single chip microcomputer is adopted in the design of DC voltage-stabilized power supply for a multifunctional, digitalized DC voltage-stabilized power supply with higher performance cost ratio. This power source uses the digital adjustment, the output precision is high. It also has short and over-current protection and alarm, which is suitable especially in each kind situation of the high accuracy request. This design intellectualization direct-current power supply uses the self-restraint keyboard entry. The single-chip microcomputer receives voltage value information of keyboard input, and caries on processing.
