High Current LED Driver From Ams OSRAM

COO (Country of Origin):
RS
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.

Stable even in coil current limit
Independent channel control
Combine channels for higher current output
PWM operation for lower output current
31.25 kHz to avoid audible noise
Long battery lifetime
High output current
