LM3560TLE-20/NOPB Datasheet PDF - TI

General Description

●The LM3560 is a 2MHz fixed frequency synchronous boost converter with two 1000 mA constant current drivers for high current white LEDs. The dual high-side current sources allow for grounded cathode LED operation and can be tied together for providing flash currents at up to 2A through a single LED.

●An adaptive regulation method ensures the current for each LED remains in regulation and maximizes efficiency.
