An Introduction of XL6005 regulator

General Description


The XL6005 LED constant current driver is a fixed frequency PWM Boost (step-up) LED constant current driver capable of controlling Series 1W/3W/5W LED modules with outstanding line and load regulation. The regulator is simple to use since it features internal frequency correction and a fixed-frequency oscillator, which means it only requires a few external components to function. At VIN>=12V, the XL6005 may directly drive 11 Series 1W LED modules. The duty ratio may be adjusted linearly from 0 to 90% using the PWM control circuit. There is an enabling function as well as an over-current protection mechanism built-in. To reduce the number of external components, an internal compensating block has been included.
