MAX17270/MAX17271

nanoPower Triple-Output, Single-Inductor,

Multiple-Output (SIMO) Buck-Boost Regulator

General Description

Beneﬁts and Features

● 3-Output, Single-Inductor, Multiple-Output (SIMO)

The MAX17270/MAX17271 are 3-output switching

regulators designed for applications requiring efficient

regulation of multiple supplies in a very small space, such

as wearable electronic devices.

Buck-Boost Regulator

● 2.7V to 5.5V Input Voltage Range

● Low-Power and Long Battery Life

• 1.3μA Operating Current (3 SIMO Channels)

• 330nA Shutdown Current

The parts use a buck-boost architecture that regulates

three outputs using a single, small 2.2µH inductor at

efficiencies up to 85%. This results in smaller board space

while delivering better total system efficiency than equivalent

power solutions using one buck and linear regulators.

• 85% Eﬃciency at 3.3V Output

● Flexible and Configurable

• I C-Compatible Interface (MAX17271)

The supply current is 0.85µA when only one output is

enabled, plus 0.2µA for each additional output enabled.

• Programmable Output Voltage: 0.8V to 5.175V

MAX17270/MAX17271

This SIMO (Single-Input Multiple-Output) regulator uti-

lizes the entire battery voltage range due to its ability to

create output voltages that are above, below, or equal to

the input voltage. Peak inductor current for each output is

programmable to optimize the balance between efficiency,

output ripple, EMI, PCB design, and load capability.

• Programmable Peak Current Limit

● Robust

• Soft-Start

• Overload Protection

• Thermal Protection

● Small Size

Two versions are available. The MAX17270 has 3 enable

inputs and 3 output voltage programming inputs. The

• 1.77mm x 1.77mm x 0.50mm, 16-Bump

0.4mm-Pitch WLP Package

• 3mm x 3mm x 0.75mm, 16-Pin TQFN Package

• Small Total Solution Size

MAX17271 includes an I C interface with interrupt, a

push-button turn on/off, and a power-good indication.

All versions are offered in either a 4 x 4, 0.4mm wafer-

level package (WLP) or a 16-pin TQFN package.

Applications

● Bluetooth Headsets

● Fitness Bands

● Watches

Ordering Information appears at end of data sheet.

● Hearables

● Wearables

● Internet of Things (IoT)

● Health Monitors
