MAX77681 - 3-Output SIMO Buck-Boost Regulator

Download the MAX77681 datasheet PDF. This datasheet also covers the MAX77680 variant, as both devices belong to the same 3-output simo buck-boost regulator family and are provided as variant models within a single manufacturer datasheet.

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).

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.

MAX77680/MAX77681 EVALUATION KIT AVAILABLE 3-Output SIMO Buck-Boost Regulator with Power Sequencer and 3μA IQ 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. The outputs are independently programmable between 0.8V and 5.25V depending on ordering option. Each output is a buck-boost with glitchless transition between buck and boost operation. The SIMO can support >300mA loads (1.8VOUT, 3.7VIN).
