MAX20310

Ultra-Low Quiescent Current PMIC with

SIMO Buck-Boost for Wearable Applications

General Description

Beneﬁts and Features

The MAX20310 is a compact power management

integrated circuit (PMIC) for space-constrained, battery-

powered applications where size and efficiency are critical.

The device combines two single inductor, multiple output

(SIMO) buck-boosted outputs with two LDOs and other sys-

tem power management features like a push-button monitor

and sequencing controller.

● Extend System Battery Use Time

• Single Inductor, Multiple Output (SIMO) Ultra-Low

Buck-Boost Regulator

• Battery Input Voltage from 0.7V to 2.0V

• Output Voltage Programmable From 0.9V

to 4.05V

• 250mW Maximum Total Input Power

• Incremental CAP Quiescent Current 1μA per

channel

The device includes a SIMO buck-boost switching regula-

tor that provides two programmable voltage rails using

a single inductor, minimizing solution footprint. The

MAX20310 operates with battery voltages down to 0.7V

for use with Zinc Air, Silver Oxide, or Alkaline batteries.

The architecture allows for output voltages above or

below the battery voltage.

• 84% Eﬃciency for 1.8V, 10mA Output

• Input Current Limited

• Dual Ultra-Low I 50mA LDO

• Inputs Supplied by Dual Buck-Boost Outputs

• Output Programmable from 0.5V to 3.65V

• Quiescent Current 1.1µA per LDO / 600nA per

Load Switch

Additionally, the MAX20310 has two programmable low-

dropout (LDO) linear regulators. The linear regulators can

also operate as power switches that can disconnect the

quiescent load of system peripherals.

• Conﬁgurable as Load Switch

● Extend Product Shelf-Life

• Battery Seal Mode

The MAX20310 includes

a programmable power

• 10nA Battery Current (typ)

controller that allows the device to be configured for

use in applications that require a true off state or for

always-on applications. This controller provides a delayed

reset signal, voltage sequencing, and customized button

timing for on/off control and recovery hard reset.

● Minimize Board Area

• 1.63mm x 1.63mm WLP

● Easy-to-Implement System Control

• Voltage Monitor Multiplexer

• 1% Accurate Battery Inverter (±10mV at 1.0V)

• Power Button Monitor

The device also features a multiplexer for monitoring the

power inputs and outputs of each function. The MAX20310

is available in a 16-bump 0.4mm pitch 1.63mm x 1.63mm

wafer-level package (WLP) and operates over the -40°C

to +85°C extended temperature range.

• Buﬀered Output

• Power Sequencing

• Reset Output

• I C Control Interface
