General Description

The MAX15053 high-efficiency, current-mode, synchro-

nous step-down switching regulator with integrated power

switches delivers up to 2A of output current. The device

operates from 2.7V to 5.5V and provides an output volt-

age from 0.6V up to 94% of the input voltage, making

the device ideal for distributed power systems, portable

devices, and preregulation applications.

The MAX15053 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 MAX15053 offers selectable skip-mode functional-

ity to reduce current consumption and achieve a higher

efficiency at light output load. The low RDS(ON) integrated

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 MAX15053 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 MAX15053 offers a capacitor-programmable soft-

start reducing inrush current, startup into PREBIAS

operations, and a PGOOD open-drain output that can be

used as an interrupt and for power sequencing.

The MAX15053 is available in a 9-bump (3 x 3 array),

1.5mm x 1.5mm WLP package and is specified over the

-40NC to +85NC temperature range.
