3-A, 4.5 to 20Vin DC/DC Converter with Adjustable Output Voltage



  • External compensation for design flexibility
  • 90% efficiency
  • 1% regulation
  • 30 mV output ripple voltage
  • Uses optional low-side MOSFET for high efficiency synchronous rectification
  • Supported by SWIFT Designer software tool for quick and easy design

Texas Instruments  TPS54350EVM-235

The TPS54350EVM-235 evaluation module allows the designer to evaluate the TPS54350 SWIFT DC/DC converter optimized for small size and low height. The inductor and capacitors selected allow a wide 6-18V input and a 3.3V output up to 3A. The output voltage can be easily adjusted for lower DSP and FPGA core voltages by changing a resistor divider. This particular design incorporates an optional low-side MOSFET (instead of a diode) to provide high efficiency synchronous rectification while switching at 500 kHz.

Please see the TPS54350EVM-235 User's Guide (SLVU097) document for more information.
