General Description

The LX1734 is an inverting DC/DC current-mode controller.

With a 750mA integrated switch, the LX1734 can generate large output currents in a small footprint.

The LX1734 minimizes external component size and cost by implementing a high switching frequency of 1.0MHz, while generating -5V at 250mA.

Key Features

  • Fixed Frequency 1.0MHz Operation.
  • Very Low Noise: 1mVP-P Output Ripple Possible With Cuk Topology.
  • Stable Operation With Ceramic or Tantalum Capacitors.
  • -5V at 250mA from 5V Input.
  • Uses Small Surface Mount L/C Components.
  • Wide Input Range: 4.2V to 8V.
  • Low VCESAT Switch: 600mV at 600mA.
  • 6-Lead 3x3mm JEDEC MLPM Package.
  • Functionally Compatible with LT1611 or LT1931.
