- DescriptionThe 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.FeaturesWide 8V to 36V Input Voltage RangeOutput Adjustable from 1.25V to 32VMaximum Duty Cycle 100%Minimum Drop Out 0.3VFixed 180KHz Switching Frequency5A Constant Output Current CapabilityInternal Optimize Power MOSFETHigh efficiency up to 96%Excellent line and load regulationBuilt in thermal shutdown functionBuilt in current limit functionBuilt in output short protection functionAvailable in TO263-5L packageApplicationsLCD Monitor and LCD TVPortable instrument power supplyTelecom / Networking EquipmentPackage includes: 1×XL4015 TO-263 Chip
