Datasheet 400KHz 60V 2A Switching Current Boost LED Constant Current Driver Features n n n n n n n n n n n n n n XL6003 General Description The XL6003 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 XL6003 could directly drive 6 Series 1W LED units at VIN>12V . Wide 3.6V to 24V Input Voltage Range 0.22V FB adjustable LED drive current Directly drive 6 Series 1W LED at VIN>=12V Fixed 400KHz Switching Frequency Max. 2A Switching Current Capability Up to 92% efficiency Excellent line and load regulation EN PIN TTL shutdown capability & With PWM Dimming Function Internal Optimize Power MOSFET Built in Soft-Start Function Built in Frequency Compensation Built in Thermal Shutdown Function Built in Current Limit Function Available in SOP8 package The PWM control circuit is able to adjust the duty ratio linearly from 0 to 95%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.
