Description

Demonstration circuit 2240A is a synchronous fourquadrantconverter featuring the LT®8714 switchingcontroller. The LT8714 can regulate to positive, negative,or zero volts when configured as a four-quadrant topology.The DC2240A regulates from a 10V to 14V inputsource to an adjustable output voltage from positive 5Vto negative 5V with a 5A maximum current rating, andoperates at 200kHz switching frequency.

Features

  • Bipolar Output Cleanly Transitions Through 0V
  • Output Can Source or Sink Current for Any Output Voltage
  • CTRL Pin Externally Sets Output Voltage
  • Wide Input Range: 4.5V to 80V
  • Power Good Indication Pin (PG)
  • Switching Frequency Up to 750kHz
  • Can Be Synchronized to an External Clock
  • High Gain EN Pin Accepts Slowly Varying Input Signals
  • 20-Lead TSSOP Exposed Pad Package

Typical applications

  • Four Quadrant Power Supplies / Bidirectional Current Sources / High Power, Low Frequency Signal Amplification
  • Test and Measurement / Electronic Window Tinting
