This is a switch steady power supply consisting of DN-24 integrated circuits. DN-25 is a power supply element of the single chip steady regulator, which is suitable for making the steady power supply of intermediate current and wide voltage range. Its main function parameters are as follows: input voltage is VIN=3～40V, output voltage is Vo=1.25～24V(can be continuously adjusted), maximum output current IOM=1A, maximum output power POM=36W, loading short limiting current IOSH≤1.1A. DN-25 is in 8-pin dual in-line package(DIP-8), whose internal circuit includes:(1) oscillator(OSC); (2)R-S trigger; (3) output switch.
