Texas Instruments LM3560
The LM3560 is a 2-MHz fixed frequency synchronous boost converter with two 1000-mA constant current drivers for high-current white LEDs. The dual highside current sources allow for grounded cathode LED operation and can be tied together for providing flash currents at up to 2 A through a single LED. The LM3560 is controlled via an I2C-compatible interface.| Part No. | LM3560 |
