MikroElektronika MIKROE-6282, High Current LED Driver From Ams OSRAM LED Driver LED Driver for AS1170 for Applications

The MikroElektronika High current driver is an inductive high efficient DCDC step up converter with two current sinks. The DCDC step up converter operates at a fixed frequency of 4 MHz and includes soft start-up to allow easy integration into noise sensitive RF systems. It includes flash timeout, overvoltage, over temperature, under voltage and short circuit protection functions. It is controlled by an I²C interface and has a hardware automatic shutdown if SCL=0 for 100 ms. Therefore no additional enable input is required for shutting down of the device once the system shuts down.
