Abstract:
A control circuit for a DC/DC converter including P-channel and N-channel transistors. The control circuit includes: a pulse generator that generates first and second pulse signals for designating turning on/off of the P-channel and N-channel transistors such that a state of the DC/DC converter or a load approaches a target value; first and second drivers that drive the P-channel and N-channel transistors based on the first and second pulse signals; first to fourth lines individually connected to an upper side power supply terminal of the first driver, a lower side power supply terminal of the second driver, a lower side power supply terminal of the first driver, and an upper side power supply terminal of the second driver; and first and second regulators that stabilize voltages of the third and fourth lines to first and second given voltage values. A coupling capacitor is connected between the third and fourth lines.

Claim (Index 10):
A system power supply, comprising:\n a direct current-to-direct current converter including\n an input terminal configured to receive an input voltage, \n a switching transistor that is a positive-channel transistor and has a first terminal connected to the input terminal, \n an inductor connected at one end thereof to a second terminal of the switching transistor, \n an output capacitor connected to an other end of the inductor, \n a synchronous rectification transistor that is a negative-channel transistor and has a first terminal connected to the one end of the inductor and a second terminal grounded, and \n a control circuit, in which the direct current-to-direct current converter is of a step-down type, and the positive-channel transistor is a switching transistor and the negative-channel transistor is a synchronous rectification transistor, configured to drive the positive-channel transistor and the negative-channel transistor.
