MAX15118
High-Efficiency, 18A, Current-Mode Synchronous
Step-Down Regulator with Integrated Switches
General Description
The MAX15118 high-efficiency, current-mode step-down
regulator with integrated power switches operates from
2.7V to 5.5V and delivers up to 18A of output current in
a small 2mm x 3.5mm package. The MAX15118 offers
excellent efficiency with skip mode capability at light-
load conditions, yet provides unmatched efficiency
under heavy load conditions. The combination of small
size and high efficiency makes this device suitable for
both portable and nonportable applications.
The MAX15118 utilizes a current-mode control architecture
with a high-gain transconductance error amplifier, which
allows a simple compensation scheme and enables a
cycle-by-cycle current limit with fast response to line and
load transients. A factory-trimmed switching frequency of
1MHz (PWM operation) allows for a compact, all-ceramic
capacitor design.
Integrated switches with low on-resistance ensure high
efficiency at heavy loads while minimizing critical induc-
tances. The MAX15118’s simple layout and footprint
assure first-pass success in new designs.
Other features of the MAX15118 include a capacitor-
programmable soft-start to reduce inrush current, safe
