<p>Disclosed is a low noise, non-isolated DC-DC converter for providing a non- inverted (i.e., the same polarity as an input voltage) output voltage of any desired voltage by stepping-up/down the input voltage. It comprises an input coil L1, an input capacitor C1 and a second intermediate coil Lm2 connected in series between both ends of the input voltage source, an output coil L2, an output capacitor C2 and a first intermediate coil Lm1 connected in series between both ends of a load Ro, a switching device S connected between a node a of the L1 and the C1 and a node b of the C2 and the Lm1, and a diode D connected between a node d of the C1 and the Lm2 and a node c of the C2 and the L2.</p> |
