XL1530降压芯片3A18V.pdf

Datasheet 3A 380KHz 18V Buck DC to DC Converter XL1530 Features General Description Wide 3.6V to 18V Input Voltage Range The XL1530 is a 380KHz fixed frequency Output Adjustable from 0.8V to 16V PWM buck (step-down) DC/DC converter, Maximum Duty Cycle 100% capable of driving a 3A load with high Minimum Drop Out 0.6V efficiency, low ripple and excellent line and Fixed 380KHz Switching Frequency load regulation. Requiring a minimum 3A Constant Output Current Capability number of external components, the regulator Internal Optimize Power MOSFET is simple to use and include internal High efficiency frequency compensation and a Excellent line and load regulation fixed-frequency oscillator. TTL shutdown capability EN pin with hysteresis function Built in thermal shutdown function The PWM control circuit is able to adjust the Built in current limit function duty ratio linearly from 0 to 100%. An enable Built in output short protection function function, an over current protection function Available in SOP8 package is built inside. When short protection function happens, the operation frequency will be reduced from 380KHz to 80KHz. An internal compensation block is built i
