LTC3675
Overview
The LTC®3675/LTC3675-1 are a digitally programmable high efficiency multioutput power supplies plus dual string LED driver ICs optimized for high power single cell Li-Ion/Polymer applications. The DC/DCs consist of four synchronous buck converters (1A/1A/500mA/500mA), one synchronous boost dc/dc (1A), and one buck-boost DC/ DC (1A) all powered from a 2.7V to 5.5V input.
- Four Monolithic Synchronous Buck DC/DCs (1A/1A/500mA/500mA)
- Buck DC/DCs Can Be Paralleled to Deliver Up to 2× Current with a Single Inductor
- Independent 1A Boost and 1A Buck-Boost DC/DCs
- Dual String I2C Controlled 40V LED Driver
- I2C Programmable Output Voltage, Operating Mode, and Switch Node Slew Rate for All DC/DCs
- I2C Read Back of DC/DC, LED Driver, Fault Status
- I2C Slave Address Options: LTC3675 = 0001001X,
