XL6005E1 60V 4A Anahtarlamalı Voltaj Yükseltici Sabit Akım Led Sürücü Entegresi

General Description
     The XL6005 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 oscillator so that it requires a minimum number of
external components to work.

     The XL6005 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.
