Overview

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 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 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 inductances. 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 startup into a prebiased output, an enable input, and a power-good output for power sequencing.

The regulator is available in a 24-bump (4 x 6), 2.1mm x 3.05mm WLP package, and is fully specified over the -40°C to +85°C extended temperature range.
