MAX77348B Datasheet Low-noise 3.5w Buck-boost Converter

Manufacturer: Analog Devices

Overview: Click here to ask an associate for production status of specific part numbers. Ultra-Low IQ, Low-Noise 3.

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

General Description

The MAX77348 is an ultra-low quiescent current, noninverting buck-boost converter capable of supporting up to 3.5W output power.

The device employs a unique control algorithm that seamlessly transitions between the buck, buck-boost, and boost modes, minimizing discontinuities and subharmonics in the output voltage ripple.

The MAX77348 is ideal for a system handling less than 3.5W output power from a single cell Li-Ion battery and requiring high system efficiency with precise voltage control.

Key Features

  • Input Voltage Range: 2.3V to 5.5V.
  • Output Voltage Range: 2.5V to 4.8V.
  • Ultra-Low, 3.5μA (typ) Quiescent Current.
  • Dynamic Voltage Scaling (DVS).
  • Optimized Load Regulation Performance.
  • Power Good Interrupt.
  • Output Active Discharge.
  • Low, Continuous Noise Profile.
  • Eliminates Discontinuities Over Operating Range.
  • Eliminates Need for Post-Filtering Low Dropout (LDO) in Noise Sensitive.
