LM5176 Datasheet Synchronous 4-switch Buck-boost Controller

Manufacturer: Texas Instruments

Overview: LM5176 SNVSAI1D – JUNE 2017 – REVISED AUGUST 2021 LM5176 55-V Wide VIN Synchronous 4-switch Buck-boost Controller.

General Description

The LM5176 is a synchronous four-switch buck-boost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage.

The LM5176 operates over a wide input voltage range of 4.2 V to 55 V (60-V absolute maximum) to support a variety of applications.

The LM5176 uses current-mode control both in buck and boost modes of operation for superior load and line regulation.

Key Features

  • Functional Safety-Capable.
  • Documentation available to aid functional safety system design.
  • Single inductor buck-boost controller for step-up/ step-down DC/DC conversion.
  • Wide VIN: 4.2 V (2.5 V with bias) to 55 V (60 V maximum).
  • Flexible VOUT: 0.8 V to 55 V.
  • VOUT short protection.
  • High efficiency buck-boost transition.
  • Adjustable switching frequency.
  • Optional frequency sync and dithering.
  • Integrated 2-A MOS.
