MAX4426/
MAX4427/MAX4428
Dual High-Speed 1.5A MOSFET Drivers
General Description
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 VDD
(see Typical 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/
MAX4427/MAX4428's high speed minimizes power loss-
es in switching power supplies and DC-DC converters.
