Title:
スイッチングレギュレータ
Document Type and Number:
Japanese Patent JP5560682
Kind Code:
B2
Abstract:
A switching power supply unit of a non-insulated, synchronous rectification type converts a voltage input to an input terminal into a predetermined voltage and outputs the voltage. The unit includes an inductor, a plurality of output switching elements, a plurality of rectifying switching elements, a switching element control circuit, a switching regulator integrated circuit, and a plurality of buffer circuits. The output switching elements, the rectifying switching elements, the switching element control circuit and the buffer circuits are integrated on the switching regulator integrated circuit.
