Beschreibung
Zusammenfassung:	The utility model relates to a signal input end of smoothed filter circuit is connected with signal output end of level conversion circuit, , including main control chip, driver chip, MOS pipe, coupling inductance, main control chip links to each other with a plurality of driver chip, and every driver chip output circuit carries out LC filtering through a coupling inductance, obtains output voltage V0, and what two MOS of every driver chip control managed opens and turn -off. The utility model discloses utilize integrated coupling inductance to replace a plurality of independent inductance, improved the dynamic behavior of CPU power supply buck converter, reduce the output current pulsation, fall the low output voltage ripple, optimize the PCB overall arrangement, improved the quality of CPU power supply buck converter from many aspects. 本实用新型涉及种基于耦合电感的Buck变换器，包括主控芯片、驱动芯片、MOS管、耦合电感，所述主控芯片与若干驱动芯片相连，每个驱动芯片输出电路通过个耦合电感进行LC滤波，得到输出电压V，每个驱动芯片控制两个MOS管的开通和关断。本实用新型利用集成的耦合电感代替多个独立电感，改善了CPU供电Buck变换器的动态性能，减少输出电流脉动，降低输出电压纹
