Generally, buck converters that cover a wide range of input and output voltages are ideal for this type of application. Specifically, this example used a 50mA synchronous buck with a 4V – 60V input range and a 0.8V up to 0.9 x Vin output range.
WebThe output voltage of an ideal buck converter is equal to the product of the switching duty cycle and the supply voltage. Like many power supply topologies, the buck converter operates on the principal of storing energy in an inductor. The voltage drop across an inductor is proportional to changes in electric current flowing through the device. WebA 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.
