Overview

The LTC3588EMSE-1#PBF is a compact power management IC targeted at energy-harvested and ultra-low-power systems. It provides integrated regulator outputs and is designed to operate from a wide input voltage range (2.7 V to 20 V) with very low standby current (950 nA). The device is offered in a 10-pin MSOP package with exposed pad suitable for space-constrained applications.

Why Choose This Part

The LTC3588EMSE-1 offers a combination of ultra-low quiescent current and a wide input-voltage window that make it well suited for harvested-energy applications. Its integrated regulator outputs reduce external component count and board area, and the exposed-pad MSOP package helps with thermal performance and grounding. The low standby current minimizes energy leakage when the harvester is idle, extending operation from small energy sources.

Applications

Batteryless / energy-harvested sensor nodes
Power supply for sensors that harvest energy from vibration, piezo, solar, or thermoelectric sources.
Wireless IoT endpoints
Provide regulated power rails for low-power radios and microcontrollers in remote wireless nodes.
Wearables and portable instrumentation
Small-package PMIC for size-constrained devices that need long standby life.
Environmental and industrial monitoring
Power management for distributed monitoring units where mains power is unavailable.
Energy-storage front end
Charge or manage a small storage element (supercap or rechargeable cell) from intermittent harvesters.

Getting Started

Start by downloading and following the datasheet and layout recommendations from the manufacturer; careful PCB layout and grounding of the exposed pad are critical for performance. Test initial designs with an adjustable bench supply or a representative energy-harvester source and measure quiescent current and cold-start behavior. Include recommended input and storage capacitors and a realistic load profile when characterizing the supply.
