摘要： In a DC-DC converter of synchronous rectifying system, a control circuit of DC-DC converter capable of improving the control voltage value of output voltage at light load and enhancing the power conversion efficiency, and its control method are presented. An inverting input terminal of comparator COMP2 of which non-inverting input terminal is connected to a grounding potential is connected to one terminal of choke coil L1 by way of terminal (X). An output terminal (N1) of comparator COMP2 is connected to a delay circuit DL, and an output terminal (N2) of delay circuit DL is connected to AND gate circuit AND1. The delay circuit DL is a circuit for delaying the transition from high level to low level of input terminal (N1). Excessive power supplied more than demanded by the load at light load is returned to choke coil L1. Elevation of output voltage VOUT due to excess power accumulated in output capacitor C1 can be suppressed.

摘要： A current charged into or discharged from a phase-compensating capacitor C1 in an output circuit is controlled by a level shift circuit so that the current is kept constant for input signals inputted to the input terminals IN+ and IN- of a differential amplifier circuit, and also a current charged into or discharged from a phase-compensating capacitor C2 is controlled by the current correcting circuit so that the current become equal to a constant current controlled by the level shift circuit, namely to a current charged into or discharged from the phase-compensating capacitor C1. Therefore, even if a quickly rising or falling signal is inputted into the differential amplifier circuit, the MOS transistor MP11 or MN11 is not set in an offset state, which prevents generation of an overshoot or an undershot in the output terminal.

摘要： A DC-DC converter includes first and second MOS transistors which selectively connect a first capacitor to a DC power supply so as to charge the first capacitor, and third and fourth MOS transistors which selectively connect the first capacitor to a second capacitor so as to charge the second capacitor by electric charges stored in the first capacitor. A predetermined output voltage is produced at a lead of the second capacitor serving as an output terminal, based on the charge/discharge operations of the first and second capacitors in response to the switching operations of the four MOS transistors. A variable voltage is applied to a back gate of one MOS transistor selected from the first to fourth MOS transistors. When the selected MOS transistor is on, a first control transistor in the converter forms a connection between a source and a back gate of the selected MOS transistor, to reduce the resistance value of the selected MOS transistor when turned on. When the selected MOS transistor is off, a second control transistor in the converter applies a voltage, selected from the predetermined output voltage and the supply voltages of the first and second DC power supplies, to the back gate of the selected MOS transistor. This prevents a parasitic bipolar transistor, inherently formed in the selected MOS transistor, from turning on.
