SWITCHING POWER SOURCE CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a switching power source circuit which can assure a power source output of a predetermined voltage in rapid and stable response to a quick and large load change. SOLUTION: The switching power source circuit supplies the input current to a load while the current is periodically switched, and variably controls the on/off time ratio (t1/t2) of the switching to control the output voltage Vo to be supplied to the load to a predetermined target value. The on/off time ratio is independently controlled at each one energizing period T. COPYRIGHT: (C)2004,JPO
