Datasheet 2A 380KHz 18V Buck DC to DC Converter Features
XL1410 General Description
The XL1410 is a 380KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2A 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 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.
Wide 3.6V to 18V Input Voltage Range Output Adjustable from 1.222V to 16V
Maximum Duty Cycle 100% Minimum Drop Out 0.6V
Fixed 380KHz Switching Frequency 2A Constant Output Current Capability Internal Optimize Power MOSFET High efficiency
Excellent line and load regulation TTL shutdown capability EN pin with hysteresis function
Built in thermal shutdown function Built in current limit function Built in output short protection function Available in SOP8 package
