降压转换器(也称为降压调节器或DC-DC步降开关稳压器)是一种输出稳压比输入电压低的DC-DC转换器。
意法半导体的单片式降压(降压)转换器IC具有高达61 V的输入电压能力,以很高的开关频率实现了高达4 A的输出电流。
为了提高MTBF(平均无故障时间)并减少外部元件,从而降低物料成本,这些降压稳压器都嵌入了全套保护功能(过流、过压和过热)。

About buck converters
How does a buck converter works ?
A buck converter usually uses two switches and an inductor to make a voltage controlled current source that interacts with the parallel combination of output capacitor and load, to generate the desired output voltage (VOUT < VIN).
Where and why is a buck converter used ?
A Buck converter is used to step down the voltage of a given input to achieve the required output voltage.
Buck converters can be used in many applications including smartphones, tablets, battery-powered equipment, industrial power systems and point-of-load supplies.
What are the advantages of a buck converter ?
Buck converters offer a more efficient solution with fewer, smaller external components. They can step-down voltages using a minimal number of components while also offering a lower operating duty cycle and higher efficiency across a wide range of input and output voltages.
