This paper describes the circuit and components of a compact board-mounted power supply module. A single-ended forward converter without a reset circuit reduces transformer size and circuit power dissipation.A simple, wide-band optoisolation circuit extends the feedback loop bandwidth and reduces the size of the output smoothing filter. A low-profile surfacemounted transformer allows the power supply module to be mounted on a 15 mm pitch circuit board.The 10-W power supply module can be reduced to 20 cc, which is half the conventional size.
