## Description

Automatic step-up-down DC-DC converter for stable power supplies, maintains the set voltage regardless of input variations, for example 12V constant at input between 5.5 and 30V. Offers adjustable output 0.5-30V, up to 30W and 3A in continuous mode, efficiency approx. 88% at 180KHz, rectification with double Schottky diodes SS56 and short-circuit protection.
The automatic voltage source module that works both as a voltage raiser and as a voltage reducer, in the 0.5-30VDC range.
It uses double Schottky diodes SS56, 60V 5A for rectification and has the advantage of keeping the output voltage regardless of the input voltage variations. For example, once the voltage is set to 12VDC, it will remain constant for an input voltage anywhere between 5.5 and 30VDC.
