Devremarkt Xl6005E1 60V 4A Anahtarlamalı Voltaj Yükseltici Sabit Akım Led

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.
