Title: Output control circuit
Inventor: AOKI NOBUHISA
IPC: H04J13/00
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To allow an output control circuit to control voltage, current and power or the like precisely in broad range, with simple configuration. SOLUTION: A first output control section 10 changes output in small scale, and an output detection section 30 detects the output of the output control circuit after changed, and the output is stored in a second output control section 20. Then the change in the first output control section 10 is restored to the original value, and the second output control section 20 changes its own output signal level for keeping the output signal level to the stored output signal level. The small scale output change by the first output control section 10 is performed with comparatively high precision, and the second output control section 20 accumulates (or decreases) the output changes in a small scale with high precision to conduct output control over a broad range with high accuracy.
