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  
2
• 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  
2
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
