Ultra Configurable PMIC Featuring 93% Peak

Efficiency Single-Inductor, 3-Output Buck-

Boost, 1-LDO for Long Battery Life

MAX77642/MAX77643

General Description

Benefits and Features

The MAX77642/MAX77643 provide power supply solu-

tions for low-power applications where size and efficiency

are critical. The IC features a SIMO buck-boost regulator

that provides three independently programmable power

rails from a single inductor to minimize total solution size.

A 150mA LDO provides ripple rejection for audio and other

noise-sensitive applications. The LDO can also be config-

ured as load switches to manage power consumption by

disconnecting external blocks when not required.

● Highly Integrated

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

Buck-Boost Regulator

• Supports Wide Output Voltage Range from 0.5V

to 5.5V for all SIMO Channels

• 1x 150mA LDO

• 100mA in LSW mode

• 2x GPIOs (MAX77643)

• Watchdog Timer (MAX77643)

The MAX77642's SIMO and LDO output voltages are in-

dividually 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. Individual enable

pins combined with the flexible resistor programmability al-

lows the device to be tailored for many applications.

● Ultra Low-Power SIMO

• 5μA Operating Current (3x SIMO Channels + 1x

LDOs)

• 1μA Operating Current per SIMO Channel

• 0.3μA Shutdown Current

• 93% Peak Efficiency in Boost-Only Mode

• 91% Peak Efficiency in Buck-Only Mode

• Less Than 20mVpp Output Ripple at V

This MAX77643's SIMO and LDO output voltages are in-

= 1.8V

OUT

dividually programmable through I C and in addition, in-

• Automatic Low-Power Mode to Normal-Power

cludes two GPIOs with alternate modes for scalability. A

Mode Transition

bidirectional I C serial interface allows for configuring and

checking the status of the devices. An internal on/off con-

troller provides a controlled startup sequence for the regu-

lators and provides supervisory functionality while they are

on. Numerous factory programmable options allow the de-

vice to be tailored for many applications, enabling faster

time to market.

● Flexible and Configurable

• Ultra-Configurable Resistor Programmable Output

Voltages (MAX77642)

• I C-Programmable Output Voltages (MAX77643)

● Small Size

• 4.24mm Wafer-Level Package (WLP)

• 25-Bump, 0.4mm Pitch, 5 x 5 Array

Applications

● Next Generation Hearables

● Fitness, Health, and Activity Monitors

● Safety and Security Monitors

● Portable Consumer Devices
