ADUM4121-1TRIZ-EP

ADuM4121-1-EP1 is a 2.3A isolated, single-channel driver that employ Analog Devices, Inc., iCoupler® technology to provide precision isolation. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and gate drivers. In comparison to gate drivers that employ high voltage level translation methodologies, the ADuM4121-1-EP offers the benefit of true, galvanic isolation between the input and the output. The ADuM4121-1-EP includes an internal Miller clamp that activates at 2V on the falling edge of the gate drive output, supplying the driven gate with a lower impedance path to reduce the chance of Miller capacitance induced turn on.

• 2.5V to 6.5V input supply voltage, 2.3A peak output current (typical) and 7.5V to 35V output
