General Description

XL6103 is a built in high frequency power

transistor and Schottky diode Boost LED

constant current driver, fixed 1.2MHz

frequency PWM, can support input operating

voltage range of 2.5V~25V. XL6103 has high

precision constant current output to drive the

LED, and built in frequency compensation

circuitry allows the use of small external

components at a price suitable for lowering

the cost of the entire power supply system

and reduce the printed circuit board space.

The low feedback voltage of 200mV reduces

the power consumption of the external

sampling resistor, and the EN pin supports

both TTL ON/OFF and PWM dimming from 0

to 100%. Suitable for very low quiescent

current and ultra-small size applications.

Applications

? Screen Backlight LED Driver
