Posted on by pinout

A Buck DC-DC converter, also known simply as a “buck converter,” is a type of switched-mode power supply (SMPS) used to convert a higher DC voltage to a lower DC voltage with increased efficiency. It’s a popular choice for voltage regulation and power conversion in a wide range of electronic devices and systems.

Description

The XL4015 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.

The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count.
