XL4001  2A 150kHz 40V Buck DC/DC Converter With Constant Current Loop

性能描述：
     The  XL4001  is  a  150KHz  fixed  frequency PWM  buck  (step-down)  DC/DC  converter, capable  of  driving  a  2A  load  with  highefficiency, 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.  An  internal  compensation block  is  built  in  to  minimize  external component count.

特点：

·  Wide 4.5V to 40V Input Voltage Range 
·  Output Adjustable from 1.235V to 37V 
·  Minimum Drop Out 1.5V 
·  Fixed 150kHz Switching Frequency 
·  2A Constant Output Current Capability 
·  Internal Optimize Power Transistor 
·  Excellent line and load regulation 
·  TTL shutdown capability 
·  ON/OFF pin with hysteresis function 
·  With output constant current loop 
·  Built in thermal shutdown function 
·  Built in current limit function 
·  Built in output over voltage protection 
·  SOP8-EP (Exposed PAD) package
