Popis: | 106 A non-inverting buck-boost DC-DC converter for USB-C charger is proposed for compact charger of the portable devices. In order to achieve the general solution for portable devices and the functional update, the pulse skipping modulation and the combined control mode used on the converter are implemented on the controller. The high voltage input, wide range output power and optional output mechanism are realized for the application. For achievement wide range output power and compact size, the proposed buck-boost converter utilizes the 0.18 μm BCD technology. The converter is consisted by power stage and control stage. The power stage is composed of four power switches of on-chip MOSFET, a low ESR off-chip inductor, and output capacitors. The controller circuit is implemented in low voltage supply to reduce the power consumption for higher efficiency. |
