MAX77681 Datasheet 3-output Simo Buck-boost Regulator

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here for production status of specific part numbers. MAX77680/MAX77681 EVALUATION KIT AVAILABLE 3-Output SIMO Buck-Boost Regulator with Power Sequencer and 3μA IQ.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX77680/MAX77681 is a 3-channel single-inductor multiple-output (SIMO) buck-boost regulator that regulates three independent rails using only 3μA of quiescent current (IQ).

The SIMO improves battery life by replacing inefficient LDOs while being competitive in efficiency to traditional single-output bucks.

The SIMO operates on a input supply between 2.7V and 5.5V.

Key Features

  • Single-Inductor, Multiple-Output (SIMO) Extends Battery Life.
  • 300nA Shutdown Current.
  • 3.0μA Operating Quiescent Current (3 SIMO Channels On).
  • Improves Overall System Efficiency while Reducing Size.
  • Maintains Regulation without Dropout unlike Traditional Bucks.
  • Glitchless Buck-Boost Operation.
  • Compact, High-Efficiency Power Solution.
  • Three Independent Channels from SIMO Regulator.
  • 2.7V to 5.5V Input Voltage Range from Singl.
