Did you know?
WebOct 1, 2024 · This example used an output voltage range of 6V – 19V and an output current of 50mA maximum. 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. The efficiency of buck converters can be very high, often over 90%, making them useful for tasks such as converting a computer's main supply voltage, which is usually 12 V, down to lower voltages needed by USB, DRAM and the CPU, which are usually 5, 3.3 or 1.8 V. See more A buck converter or step-down converter is a DC-to-DC converter which steps down voltage (while stepping up current) from its input (supply) to its output (load).
