MAX77640/MAX77641

Ultra-Low Power PMIC with 3-Output SIMO,

150mA LDO, and Power Sequencer

General Description

Benefits and Features

The MAX77640/MAX77641 are a low-I power solution

● Compact, High-Efficiency Power Solution

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

Buck-Boost Regulator

for applications where size and efficiency are critical. The

device integrates a 3-output single-inductor multiple-out-

put (SIMO) buck-boost regulator, a 150mA LDO, and a

3-channel current-sink driver.

• 150mA LDO

• 3-Channel Current-Sink Driver

• Flexible Power Sequencing

• GPIO and Reset Output

The SIMO operates on an input between 2.7V and 5.5V.

The outputs are independently programmable between

0.8V and 5.25V depending on ordering option. Each out-

put is a buck-boost with glitchless transition between buck

and boost operation. The SIMO can support >300mA

● 3-Output SIMO Extends Battery Life

• 2.7V to 5.5V Input Voltage Range from Single Cell

Li-Ion

loads (1.8V

, 3.7V ).

• 0.8V to 5.25V Output Voltage Range (Table 1)

OUT

• Supports >300mA loads (1.8V

• Improves Overall System Efficiency while Reducing

Size

• Maintains Regulation without Dropout unlike

Traditional Bucks

• Glitchless Buck-Boost Operation

, 3.7V )

OUT

The 150mA LDO provides ripple rejection for noise-sen-

sitive applications. The current sinks can be programmed

to blink LEDs in custom patterns. The device integrates

a power sequencer to control power-up/down order of

each output. Default output voltages and sequence order

are factory-programmable. An I C serial interface further

configures the device.

● Low Quiescent Current

• 300nA Shutdown Current

• 5.6μA Operating Current (3 SIMO Channels and

LDO On)

The MAX77640/MAX77641 are available in a 30-bump

wafer-level package (WLP). Total solution size is 16mm .

For a similar product with a battery charger, refer to the

MAX77650.

● Small Size

• 2.75mm x 2.15mm (0.7mm max heigh) WLP

• 30-Bump, 0.4mm Pitch, 6 x 5 Array

• 16mm Total Solution Size

Applications

● Hearables: Bluetooth Headphones and Earbuds

● Wearables: Fitness, Health, and Activity Monitors

● Action Cameras, Wearable/Body Cameras

● Internet of Things (IoT) Gadgets
