MAX15112
High-Efficiency, 12A, Current-Mode Synchronous
Step-Down Regulator with Integrated Switches
General Description
The MAX15112 high-efficiency, current-mode step-down
regulator with integrated power switches operates from
2.7V to 5.5V and delivers up to 12A of output current in a
small 2mm x 3mm package. The MAX15112 offers excel-
lent efficiency with skip mode capability at light-load con-
ditions, 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 MAX15112 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 MAX15112’s simple layout and footprint
assure first-pass success in new designs.
Other features of the MAX15112 include a capacitor-
programmable soft-start to reduce inrush current, safe
