A buck converter, or a step-down converter, is a power converter that produces the output voltage smaller than the input voltage. But why exactly is it called a buck converter?
Well, it's called that way
Buck 3 click
Buck 3 click is a very advanced synchronous step-down (buck) converter, which is designed to deliver noise and ripple-free voltage to highly sensitive applications, such as FPGA and high-performance DSP platforms.
Buck 3 click carries the TPS658215 synchronous step-down SWIFT™ converter from Texas Instruments.
Voltage range - the input voltage range goes from 4.5V to 17V. Clean, noiseless and ripple-free 3.3V output is provided by the D-CAP3™ PWM control mode.
This Click board™ also features overvoltage and undervoltage protection, thermal protection, current limiting, and more.
