Abstract

The invention belongs to the technical field of power electronics, and discloses a dual-output DC-DC converter, which comprises a voltage source, a first inductor, a boost converter, a buck converter and a first capacitor, wherein the boost converter comprises a first MOS tube, a second MOS tube, a second inductor, a third inductor and a PWM controller, and the buck converter comprises a PFM controller and a plurality of switched capacitor converters. The boost converter and the buck converter are mixed, the advantages of the boost converter and the buck converter can be well fused, the disadvantages of the boost converter and the buck converter can be well overcome, and then two voltage-stabilized output voltages can be provided from a single-input power supply with large change. In the structure, the input of the buck converter is adjusted by the boost converter, is not influenced by the change of a primary input feeder line, and the buck converter always works under a fixed input voltage in a voltage reduction stage, so that the design is optimized, and the power is improved.

Description

technical field [0001] The invention belongs to the technical field of power electronics and relates to a double-output DC-DC converter. Background technique [0002] In the past two decades, the unprecedented development of semiconductor technology has led to the proliferation of portable solutions in the consumer electronics and wireless electronics markets. The device size has been continuously reduced to below a few hundred nanometers, enabling the integration of various subsystems on a single chip. Thus forming a compact system-on-chip. However, this tightly packed mixed-signal integration on a single silicon die brings with it several design requirements and associated challenges, one of which is the need for multiple on-chip power domains. [0003] Currently, these portable devices are mainly powered by rechargeable batteries, and the output voltage of a fully charged battery drops slowly over time, which places special requirements on the DC-DC converters of portabl...
