High-Efficiency, 3A, Current-Mode
Synchronous, Step-Down Switching Regulator
General Description
The MAX15058 high-efficiency, current-mode, synchro-
nous step-down switching regulator with integrated
power switches delivers up to 3A of output current.
The device operates from 2.7V to 5.5V and provides an
output voltage from 0.6V up to 94% of the input voltage,
making the device ideal for distributed power systems,
portable devices, and preregulation applications.
The MAX15058 utilizes a current-mode control archi-
tecture with a high-gain transconductance error ampli-
fier. The current-mode control architecture facilitates
easy compensation design and ensures cycle-by-cycle
current limit with fast response to line and load transients.
The MAX15058 offers selectable skip-mode functional-
ity to reduce current consumption and achieve a higher
efficiency at light output load. The low R DS(ON) inte-
grated switches ensure high efficiency at heavy loads
while minimizing critical inductances, making the layout
design a much simpler task with respect to discrete
solutions. Utilizing a simple layout and footprint assures
first-pass success in new designs.
The MAX15058 features a 1MHz, factory-trimmed, fixed-
frequency PWM mode operation. The high switching fre-
quency, along with the PWM current-mode architecture,
allows for a compact, all-ceramic capacitor design.
The MAX15058 offers a capacitor-programmable soft-
