MAX38640/1/2/3/A/B

Tiny 1.8V - 5.5V Input, 330nA I , 700mA

nanoPower Buck Converter

General Description

Benefits and Features

The MAX3864xA/B are nanoPower family of ultra-low

330nA quiescent current buck (step-down) DC-DC con-

verters operating from 1.8V to 5.5V input voltage and sup-

porting load currents of up to 175mA, 350mA, 700mA with

peak efficiencies of 96%. While in shutdown, there is only

5nA of shutdown current. The devices offer ultra-low qui-

escent current, small total solution size, and high efficien-

cy throughout the load range. The MAX3864xA/B are ide-

al for battery applications where long battery life is a must.

● Extends Battery Life

• 330nA Ultra-Low Quiescent Supply Current

• 5nA Shutdown Current

• 96% Peak Efficiency and Over 88% at 10µA

● Easy to Use – Addresses Popular Operation

• 1.8V to 5.5V Input Range

• Preprogrammed V

• Single Resistor Adjustable V

• ±1.75% Output Voltage Accuracy

from 0.5V to 5V

OUT

from 0.7V to 3.3V

OUT

The MAX3864xA/B family utilizes a unique control scheme

that allows ultra-low quiescent current and high efficiency

over a wide output current range. MAX38642 excludes ac-

tive discharge resistor in shutdown which allows the out-

put to be regulated or held high by another source or by

the charged output capacitor.

• Up to 175mA/350mA/700mA Load Current

● Protects System in Multiple Use Cases

• Reverse-Current Blocking in Shutdown

• Optional Active Discharge Feature

● Reduces Size and Increases Reliability

• -40°C to +85°C Temperature Range

The MAX3864xA/B devices are offered in a space-saving

1.42mm x 0.89mm 6-pin wafer-level package (WLP) (2

x 3 bumps, 0.4mm pitch), as well as a 2mm x 2mm,

6-pin µDFN package. All parts are specified from -40°C to

+85°C.

• 2mm x 2mm 6-pin µDFN Package

• 1.42mm x 0.89mm, 0.4mm Pitch 6-pin (2 x 3) WLP

Ordering Information appears at end of data sheet.
