XL6001 General Description
The XL6001 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W 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 XL6001 could directly drive 5~8 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.

XL6001 Pin Description
XL6001 Pin Number | XL6001 Pin Name | XL6001 Description |
1 | EN |
Enable Pin. Drive EN pin low to turn off the device, drive it high to turn it on. Floating is default high. |
2 | VIN |
Supply Voltage Input Pin. XL6001 operates from a 3.6V to 24V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. |
3 | FB | Feedback Pin (FB). The feedback threshold voltage is 0.22V.
|
4 | NC | No Connected.
|
5、6 | SW |
Power Switch Output Pin (SW). Output is the switch node that supplies power to the output. |
7、8 | GND | Ground Pin.
