用于升压型直流-直流转换器内的半导体装置和该转换器
摘要：
公开了在使用中能够满足装置功率需求和具有高效率的电源装置。该电源装置包括第一电源；提高第一电源输出电压的电压升压单元；降低电压升压单元的输出电压的电压降压单元；以及通过电压降压单元的输出电压驱动工作的负载。所述电压升压单元将第一电源的输出电压提升至电压降压单元操作电压的下限值。
摘要（英）：

A power supply device is disclosed that is able to satisfy the power requirements of a device in service and has high efficiency. The power supply device includes a first power supply; a voltage step-up unit that steps up an output voltage of the first power supply; a voltage step-down unit that steps down an output voltage of the voltage step-up unit; and a load that is driven to operate by an output voltage of the voltage step-down unit. The voltage step-up unit steps up the output voltage of the first power supply to a lower limit of an operating voltage of the voltage step-down unit.
