2.2MHz, 3A Buck or Boost Converters
with an Integrated High-Side Switch
General Description
The MAX15036/MAX15037 high-frequency, DC-DC con-
verters with an integrated n-channel power MOSFET
provide up to 3A of load current. The MAX15036
includes an internal power MOSFET to enable the
design of a nonsynchronous buck or boost topology
power supply. The MAX15037 is for the design of a
synchronous buck topology power supply. These
devices operate from a 4.5V to 5.5V or 5.5V to 23V
input voltage and offer the ability to set the switching
frequency from 200kHz to 2.2MHz with an external
resistor. The voltage-mode architecture with a peak
switch current-limit scheme provides stable operation
up to a 2.2MHz switching frequency. The MAX15036
includes a clock output for driving a second DC-DC
converter 180° out-of-phase and a power-on-reset
( RESET ) output. The MAX15037 includes a power-good
output and a synchronous rectifier driver to drive an
external low-side MOSFET in the buck converter config-
uration for high efficiency.
The MAX15036/MAX15037 protect against overcurrent
conditions by utilizing a peak current limit as well as
overtemperature shutdown providing a very reliable
and compact power source for point-of-load regulation
applications. Additional features include synchroniza-
