MAX16962

4A, 2.2MHz, Synchronous Step-Down

DC-DC Converter

General Description

The MAX16962 is a high-efficiency, synchronous step-

down converter that operates with a 2.7V to 5.5V input

voltage range and provides a 0.8V to 3.6V output voltage

range. The wide input/output voltage range and the abil-

ity to provide up to 4A to load current make this device

ideal for on-board point-of-load and post-regulation

applications. The MAX16962 achieves -3.7%/+2.6% out-

put error over load, line, and temperature ranges.

The MAX16962 features a 2.2MHz fixed-frequency PWM

mode for better noise immunity and load transient

response, and a pulse frequency modulation mode

(SKIP) for increased efficiency during light-load opera-

tion. The 2.2MHz frequency operation allows for the use

of all-ceramic capacitors and minimizes external compo-

nents. The optional spread-spectrum frequency modula-

tion minimizes radiated electromagnetic emissions.

Integrated low R

DSON

switches improve efficiency at

heavy loads and make the layout a much simpler task

with respect to discrete solutions.

The MAX16962 is offered with factory-preset output

voltages or with an adjustable output voltage. (See the

Selector Guide

for options). Factory preset output volt-

age versions allow customers to achieve -3.7%/+2.6%

output voltage accuracy without using external resistors,

while the adjustable output voltage version provides the

flexibility to set the output voltage to any desired value

between 0.8V to 3.6V using an external resistive divider.

Additional features include 8ms soft-start, 16ms power-

good output delay, overcurrent, and overtemperature

protections.

The MAX16962 is available in thermally enhanced

16-pin TSSOP-EP and 4mm x 4mm, 16-pin

TQFN-EP packages, and is specified for operation over

the -40NC to +125NC automotive temperature range.
