LM5175 - Synchronous 4-Switch Buck-Boost Controller

General Description

The LM5175 is a synchronous four-switch buck-boost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage.

The LM5175 operates over a wide input voltage range of 3.5 V to 42 V (60 V maximum) to support a variety of applications.

Key Features

  • 1 Single Inductor Buck-Boost Controller for StepUp/Step-Down DC/DC Conversion.
  • Wide VIN Range: 3.5 V to 42 V, 60 V Maximum.
  • Flexible VOUT Range: 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 MOSFET Gate Drivers.
  • Cycle-by-Cycle Current Limit and Optional Hiccup.
  • Optional Input or Output Averag.
