The MAX15054 is a high-side, n-channel MOSFET driver

for high-voltage applications capable of switching at high

frequencies. This device is controlled by a CMOS logic-

level signal referenced to ground and features a very

short (12ns, typ) propagation delay from input to output.

The high-voltage operation and high source/sink-current

capability make the MAX15054 ideal for HB LED drivers

and DC-DC converters.

The MAX15054 is well suited to complement other Maxim

LED driver products such as the MAX16814, MAX16838,

MAX16833, MAX16834, and MAX16826. The MAX15054

adds a high-side driver to those products that include only a

low-side driver; it then allows for buck-boost configurations

for multistring drivers similar to the MAX16814, MAX16838,

and MAX16826, and for buck-boost conversion with output

referenced to ground for single-string drivers such as the

MAX16834 and MAX16833.

The MAX15054 is

SOT23 package and operates over the -40NC to +125NC

automotive temperature range.
