Ultra-Configurable SIMO PMIC Featuring

3-Output Buck-Boost, 1-LDO for Long Battery

Life Primary Cell Applications

MAX77646/MAX77647

General Description

Benefits and Features

The MAX77646/MAX77647 provides power supply solu-

tions for low-power applications where size and efficiency

are critical. The IC features a Single Inductor Multiple Out-

put (SIMO) buck-boost regulator that provides three inde-

pendently programmable power rails from a single induc-

tor to minimize total solution size. A 150mA LDO provides

ripple rejection for audio and other noise-sensitive appli-

cations. The LDO can also be configured as a load switch

to manage power consumption by disconnecting external

blocks when not required.

● 1.8V to 3.3V Input Range

● Highly Integrated

• 3x Output, Single Inductor Multiple Output (SIMO)

Buck-Boost Regulators

• Supports Wide Output Voltage Range from 0.5V

to 5.1V for all SIMO Channels

• 1x 150mA LDO

• 100mA in LSW Mode

• 2x GPIOs (MAX77647)

• Watchdog Timer (MAX77647)

The MAX77646/MAX77647 operates with battery voltages

from 1.8V with coin-cell, dual silver oxide, dual alkaline,

● Ultra Low-Power SIMO

• 1.3μA Operating Current (3x SIMO Channels)

• 0.1μA Shutdown Current

and LiSOCL primary batteries.

• 85% Efficiency in Buck-Only Mode (V = 2.4V,

The MAX77646 (R

variant) SIMO and LDO output volt-

SEL

OUT

= 0.8V,10mA, I = 0.5A)

ages are individually programmable through resistors. A

peak current limit input is used to set both the inductor's

peak current limits of the device with a single resistor. Indi-

vidual enable pins combined with the flexible resistor pro-

grammability allows the device to be tailored for many ap-

plications.

• 86% Efficiency in Buck-Boost Mode (V = 2.4V,

OUT

= 1.8V,10mA, I = 0.5A)

• Less Than 20mVpp Output Ripple at V

= 1.8V

OUT

• Automatic Low-Power Mode to Normal-Power

Mode Transition

● Flexible and Configurable

The MAX77647 (I C variant) SIMO and LDO output volt-

Voltages (MAX77646)

ages are individually programmable through I C and in

addition, includes two GPIOs with alternate modes for

scalability. A bidirectional I C serial interface allows for

• I C-Programmable Output Voltages (MAX77647)

configuring and checking the status of the devices. An in-

ternal on/off controller provides a controlled startup se-

quence for the regulators and provides supervisory func-

tionality while they are on. Numerous factory programma-

ble options allow the device to be tailored for many appli-

cations, enabling faster time to market.

● Small Size

• 5mm Wafer-Level Package (WLP)

• 20-Bump, 0.5mm Pitch, 5 x 4 Array

Applications

● GNSS Module

● IoT Enabled Wireless Sensor Nodes

● Home Safety and Security Monitors

● Factory Safety and Security Monitors

● Fitness, Health, and Activity Trackers
