XL1513 2A 380KHz 18V Buck DC to DC Converter
性能描述：
The XL1513 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 funion, an over current proteion funion is built inside. When short proteion funion happens, the operation frequency will be reduced from 380KHz to 80KHz. An internal compensation block is built in to minimize external component count.
特点：
• Wide 3.6V to 18V Input Voltage Range
• Output Adjustable from 0.8V to 16V
