Description
Datasheet 5A 180KHz 36V Buck DC to DC Converter Features Wide 8V to 36V Input Voltage Range Output Adjustable from 1.25V to 32V Maximum Duty Cycle 100% Minimum Drop Out 0.3V Fixed 180KHz Switching Frequency 5A Constant Output Current Capability Internal Optimize Power MOSFET High efficiency up to 96% Excellent line and load regulation Built in thermal shutdown function Built in current limit function Built in output short protection function Available in TO263-5L package XL4015 General 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 ins […]
