Description
buck-boost power supply
Wide voltage input 5.5-30V, wide voltage output 0.5-30V, can be boosted or stepped down. If you adjust the output voltage to 18V, then the input voltage will change between 5.5-30V and will output a constant 18V; then, for example, You input 12V, adjust the potentiometer to set any output of 0.5-30V.
The external 60V75A high power MOS is used, and the high current and high voltage Schottky diode SS56 is connected in parallel. The 6009 or 2577 program SS34 can be compared because the MOS and Schottky voltages are greater than the sum of the input and output voltages, depending on the boost and buck principles. Iron silicon aluminum magnetic ring inductance, high efficiency.
