High-Efficiency, 8A, Current-Mode

Synchronous Step-Down Switching Regulator

General Description

Features

The MAX15108 high-efficiency, current-mode, synchro-

nous step-down switching regulator with integrated

power switches delivers up to 8A of output current. The

regulator operates from 2.7V to 5.5V and provides an

output voltage from 0.6V up to 95% of the input voltage,

making the device ideal for distributed power systems,

portable devices, and preregulation applications.

S Continuous 8A Output Current

S Efficiency Up to 96%

1% Accuracy Over Load, Line, and Temperature

S Operates from a 2.7V to 5.5V Supply

S Adjustable Output from 0.6V to 0.95 x V

S Programmable Soft-Start

The IC utilizes a current-mode control architecture

with a high gain transconductance error amplifier.

The current-mode control architecture facilitates easy

compensation design and ensures cycle-by-cycle

current limit with fast response to line and load transients.

S Safe Startup into Prebiased Output

S External Reference Input

S 1MHz Switching Frequency

S Stable with Low-ESR Ceramic Output Capacitors

S Skip Mode or Forced PWM Mode

The regulator offers a selectable skip-mode functionality

to reduce current consumption and achieve a higher effi-

S Enable Input and Power-Good Output for Power-

ciency at light output load. The low R

integrated

DS(ON)

Supply Sequencing

switches ensure high efficiency at heavy loads while

minimizing critical inductance, making the layout design

a much simpler task with respect to discrete solutions.

The IC’s simple layout and footprint assures first-pass

success in new designs.

S Cycle-by-Cycle Overcurrent Protection

S Fully Protected Features Against Overcurrent and

Overtemperature

S Input Undervoltage Lockout

The regulator features a 1MHz, factory-trimmed fixed-

frequency PWM mode operation. The high switching

frequency, along with the PWM current-mode architecture

allows for a compact, all ceramic capacitor design.

S 20-Bump (4 x 5 Array), 2.5mm x 2mm, WLP

Package

The IC features a capacitor-programmable soft-start

to reduce input inrush current. Internal control circuitry

ensures safe-startup into a prebiased output. Power

sequencing is controlled with the enable input and

power-good output.
