Abstract
This design is a digital adjustable DC voltage stabilization supply, whose output
voltage can be adjusted and controlled.The voltage increase is 74LS193, The system is
composed of auxiliary power supply, input keyboard circuit, single chip control circuit,
digital - mode conversion circuit, and output voltage stabilization circuit. The output
voltage adjustment includes two pulses and button operation, reversible counter makes
add and decrease counting is divided into two parts: di
