2A 380KHz 18V Buck DC to DC Converter--XL1410
General Description
The XL1410 is a 380KHz fixed frequency PWM buck (step-down) DC/DCconverter,capable of driving a 2A load with highefficiency, 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 enable
function, an over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 380KHz to 80KHz. An internal compensation block is built in to minimize external component count.
