Abstract:
A DC-DC converter, which allows a current to pass through an inductor and rectifies the current through the inductor to convert an input direct current voltage supplied from a direct current power unit into a direct current voltage at a different potential and output the direct current voltage, includes a switching control circuit performing peak-current control procedures including turning on the switching element when the converted direct current voltage drops to a predetermined potential and turning off the switching element when the current through the inductor reaches a predetermined value. The converter includes a copied-current generating circuit generating a current proportional to the output current. The switching control circuit turns off the switching element when the circuit detects that the current through the inductor reaches a predetermined value with reference to a combined current of the copied current generated at the copied-current generating circuit and a predetermined reference current.

Claim (Index 7):
The DC-DC converter according to  claim 5 , wherein:\n the switching control circuit further comprises a divider circuit dividing an output voltage to generate a feedback voltage and a circuit generating a signal to provide timing for turning on the switching element when the feedback voltage reaches a predetermined potential, the divider circuit is capable of varying a voltage division ratio and determines the output voltage in response to the voltage division ratio of the divider circuit, the current detection circuit comprises field effect transistors provided in parallel, the field effect transistors having the same conductivity type as that of the switching element, and a combined current of the copied current and the reference current passing through the field effect transistors, and the field effect transistors selectively operate in response to the voltage division ratio of the divider circuit such that the drain voltage of the switching element varies when the switching element is switched off.
