The MAX4426/MAX4427/MAX4428 are dual monolithic MOSFET drivers designed to translate TTL/CMOS inputs to high voltage/current outputs. The MAX4426 is a dual inverting power MOSFET driver. The MAX4427 is a dual noninverting power MOSFET driver, and the MAX4428 contains one inverting section and one noninverting section. Delay times are nearly independent of V_DD (see Typical Operating Characteristics in the full data sheet). High-current output drivers rapidly charge and discharge the gate capacitance of even the largest power MOSFETs to within millivolts of the supply rails. This produces the power MOSFETs' minimum on resistance. The MAX4426/MAX4427/MAX4428's high speed minimizes power losses in switching power supplies and DC-DC converters.
