一,产品概述(General Description)      

   The CXLE8605 regulator is fixed frequency PWM Boost (step-up) LED
constant current driver, capable of driving Series 1W/3W/5W LED units with excellent line and load regulation. The regulator is simple to use because it
includes internal frequency compensation and a fixed-frequency oscillatorBCf嘉泰姆

so that it requires a minimum number of external components to work.
   The CXLE8605 could directly drive 16 Series 1W/3W LED units at VIN=24V . 
   The CXLE8604 regulator is fixed frequency PWM Boost (step-up) LED constant current driver,capable of driving Series 1W/3W/5W LED units with excellent

internal frequency compensation and a fixed-frequency oscillator so that it
requires a minimum number of external components to work.
     The CXLE8604 could directly drive 11 Series 1W LED units at VIN>12V .
     The PWM control circuit is able to adjust the duty ratio linearly from 0 to
90%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.BCf嘉泰姆
