Title: Switching power circuit
Inventor: HAYASHI HIROSHI
IPC: H02M3/155
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To increase a voltage changing efficiency by connecting the base of a transistor to the input side and controlling the on/off of the transistor by a detecting means which detects whether the voltage at the output side is specified value or above. SOLUTION: When the output voltage VO of an output capacitor C3 exceeds 5V and the potential at the point (a) becomes the threshold value of a transistor Q3 or above, the transistor Q3 turns on and thereby a transistor Q2 turns off and then a transistor Q1 turns off, too. Even if the transistor Q1 becomes an off state, a coil L1 tries to allow current to flow by its electromotive force. This current is caused to flow from the ground side when a diode D1 turns on. It is also caused to flow by the discharging of the capacitor C1. When the output voltage VO becomes 5V or below, the transistor Q3 turns off and the transistors Q1 and Q2 turn on. By repetition of the switching operations in this manner, the output voltage is kept at VO.
