<p><P>PROBLEM TO BE SOLVED: To provide a thin DC/DC converter with low noise which can supply stable DC power to a load of an electronic unit. <P>SOLUTION: The thin DC/DC converter is composed of a coil 2, a bare chip IC 2, a resistor 4 and a capacitor 4a. The coil 2, the bare chip IC 3, the resistor 4 and the capacitor 4a are mounted on a box-shaped microwave circuit where a circuit pattern is formed on a plane of a resin mold made of an insulator. <P>COPYRIGHT: (C)2004,JPO</p> |
