Title: Dc-dc converter
Inventor: USUI HIROSHI
IPC: H02M3/28
Filed: 1994-10-31
Abstract: PURPOSE: To reduce the switching loss by intermittently controlling a switching element, based on the comparative output between the reference voltage level for stabilization at the time of relatively low load lower than the level of the reference voltage for stabilization and the output voltage. CONSTITUTION: When a switch 21 is turned on at the time of light load during waiting, an error amplifier 22 is turned on, and a photocoupler 24 operates, and the voltage level of the non-inverting input terminal of the error amplifier 22 drops. Therefore, the output of the error amplifier 22 drops, and the drive signal to the switching elements 3 and 4 of a control circuit 2 stops, and at this time, the DC-DC converter suspends its operation intermittently. Accordingly, the output voltage to load drops, and when it reaches the reference voltage of a reference power source 23 for a light load, the error amplifier 22 is turned off, and the control circuit 22 generates a drive signal to the switching elements 3 and 4, again. Thereafter, this operation is repeated, and it is kept roughly constant at the output voltage being decided by the reference voltage of the reference power source 23 for the light load.
