Switching driving circuit and driving method of switching driving circuit
A switching driving circuit includes a switch configured to switch a current supplied to a target circuit, a sensing resistor connected to the switch, a controller configured to control the switch by comparing a sensing voltage applied to the sensing resistor with a reference voltage, and a compensa...

Zusammenfassung: | A switching driving circuit includes a switch configured to switch a current supplied to a target circuit, a sensing resistor connected to the switch, a controller configured to control the switch by comparing a sensing voltage applied to the sensing resistor with a reference voltage, and a compensation circuit configured to regulate the reference voltage based on an amount of variation of an input voltage input into the target circuit and an output voltage output from the target circuit. |
