A switch mode DC-DC converter 600 has a power switch 101, 102 connected between a supply node 119, 120 and an inductor node 121. The DC-DC converter has switch control circuitry 612, 614, 615 for driving the power switch to controllably vary the rate of at least one of turn-on or ...
A switch mode DC-DC power converter comprises at least one first electronic circuit on a first side (1) and a second electronic circuit on a second side (2). The first side (1) and the second side (2) are coupled via at least two power transformers (T1, T2). Each power transformer...
