LM5122EVM-1PH Wide Vin Synchronous Boost Controller Evaluation Module

Overview

TopologyBoost Converter
Input voltage9-20 V
Output 128 V / 7 A

Description

The LM5122EVM-2PH evaluation module (EVM) provides the design engineer with a fully functional dual phase synchronous boost converter to evaluate the Texas Instruments LM5122 synchronous boost controller device. The EVM provides 28 V output at up to 7 A current from a 9 V to 20 V input. The EVM isdesigned to start up from a single power supply without any additional bias voltage.

Features

  • 9 V to 20 V input voltage range
  • 28 V target output voltage
  • Up to 7 A output current
  • 250 kHz typical switching frequency
  • Dual phase interleaved operation

Typical applications

  • Automotive Start-Stop
  • 12-V, 24-V, and 48-V Power Systems, High-Current Boost Power Supply, Audio Power Supply
