Title: ISOLATED-TYPE DC-DC CONVERTER
Abstract:
Provided is an isolated-type DC-DC converter which occupies a small surface area on a mother board. This isolated-type DC-DC converter (200) includes: a board (1); a transformer (13); primary-side electronic components and primary-side wiring which, in conjunction with a primary-side winding (13P), form a primary-side circuit; secondary-side electronic components, including a choke coil (14), and secondary-side wiring which, in conjunction with a secondary-side winding (13S) form a secondary-side circuit isolated from the primary-side circuit; and inter-circuit electronic components and primary-side inter-circuit wiring which are connected straddling the primary-side circuit and the secondary-side circuit while galvanically isolating the primary-side circuit and the secondary-side circuit. The choke coil (14) is disposed separated from one main surface of the board 1. At least one electronic component selected from among the primary-side electronic components and the inter-circuit electronic components, and part of the primary-side wiring and/or part of the primary-side inter-circuit wiring are disposed between the choke coil (14) and said one main surface of the board (1).
