图1TPS630252内部结构图

TPS630252 Single Inductor Buck-Boost Converters are high efficiency, low quiescent current converters suitable for applications where the input voltage is higher or lower than the output. Output currents can go as high as 2A in boost mode and as high as 4A in buck mode.

图2TPS630252参考设计图

The maximum average current in the switches is limited to a typical value of 4A. The TPS630252 regulates the output voltage over the complete input voltage range by automatically switching between buck or boost mode.
