High-Side MOSFET Driver for HB LED Drivers
and DC-DC Applications
General Description
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 available in the industry-standard 6-pin
SOT23 package and operates over the -40 N C to +125 N C
automotive temperature range.
