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 pensation circuitry allows the use of small external ponents 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 200m V 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
- Wearable Portable Electronic Devices
- Digital Cameras
- PDAs and Other Handheld Devices
- Auxiliary Displays
