IPC: H01L21/8232
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an IC for a switching power supply which ensures feeding power during transient when switching from a primary power supply to a secondary power supply of a switching control circuit. SOLUTION: An intermediate electrode TAP is placed not at a common point between a source 51s for a JEFT 1 and a drain 52d of ana IGFET connected in series but at an exclusive source 55s for a JFET 3 connected to a JFET 2 in series which commonly uses a drain of the JFET 1. Since the intermediate electrode TAP is not grounded though the IGFET is turned on, the current taken out of the electrode TAP (starting current of a switching circuit 13) is not interrupted and can be continuously fed regardless of on or off state of the IGFET. Accordingly, there is not risk of interruption of power supply at the time of switching of the power supply by the switching control circuit 13 and the reliability of the power supply operation can be increased.
