Typical Operating Circuit

General Description

The MAX4426/4427/4428 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 noninvert-

ing power MOSFET driver, and the MAX4428 contains

one inverting section and one noninverting section.

Operating Characteristics). 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 MAX4426/4427/4428's high

speed minimizes power losses in switching power sup-

plies and DC-DC converters.
