LM5115 - Secondary Side Post Regulator / Synchronous Buck Controller

General Description

The LM5115 is a versatile switching regulator controller.

It has two main application configurations.

The first is utilizing the Secondary Side Post Regulation (SSPR) technique to implement multiple output power converters.

Key Features

  • 1.
  • 2 Self-Synchronization to Main Channel Output.
  • Standalone DC/DC Synchronous Buck Mode.
  • Leading Edge Pulse Width Modulation.
  • Voltage-Mode Control with Current Injection and Input Line Feed-Forward.
  • Operates from AC or DC Input up to 75V.
  • Wide 4.5V to 30V Bias Supply Range.
  • Wide 0.75V to 13.5V Output Range.
  • Top and Bottom Gate Drivers Sink 2.5A Peak.
  • Adaptive Gate Driver Dead-Time Control.
  • Wide Bandwidth E.
