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 high-side 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. An adaptive regulation method ensures the current for each LED remains in regulation and maximizes efficiency.The LM3560 is controlled via an I2C-compatible interface. Features include an internal 4-bit ADC to monitor the LED voltage, independent LED current control, a hardware flash enable allowing a logic input to trigger the flash pulse, dual TX inputs which force the flash pulse into a low-current torch mode allowing for synchronization to RF power amplifier events or other high-current conditions, and an integrated comparator designed to monitor an NTC thermistor and provide an interrupt to the LED current. Additionally, an active high HWEN input provides a hardware shutdown during system software failures. The device is available in an ultra-small 16-pin DSBGA package. The 2-MHz switching frequency, overvoltage protection and adjustable current limit allow for the use of tiny, low-profile (1-μH and 2.2-μH) inductors and ceramic (10-μF) capacitors.For all available packages, see the orderable addendum at the end of the data sheet.
