Project: 50 Watt per square inch high power density DC/DC converter

 

Design Services Performed:

Description:

This 50 Watt Step down (buck) power converter is packaged into less than 1 square inch. This state of the art power density is achieved by the use of the latest semiconductors, inductors and over 20 years of power supply design experience. A relatively low switching frequency allows the switching waveform edges to be kept slower than MHz converters - these slow switching edges significantly reduce peak-peak noise and the EMI emissions without lowering efficiency. Flexible input voltages from 5 to 36 VDC and adjustable output voltages from 0.8 to 9 volts at up to 10 Amps / 50 Watts allow for many uses with the same basic design. Other features are integral poly-phase clock-in and clock out signals

  • 5-36 VDC input / 0.8-9 VDC output at 10 amps up to 50 watts.
  • Up to 96% efficiency.
  • Completely short circuit to ground protected.
  • Low noise 250 KHz switching frequency (syncronizable from 150-500 kHz)
  • Direct poly-phase operation.
  • 20 mV p-p output noise for a 5 Volt / 10 Amp output.
  • Fully input and output filtered.
  • No external components required.
  • Designed for flexible volume manufacturing line.
  • Very low parts count / low semiconductor unction temperature.
  • Environmentally rugged design, -40 to 70 Deg C operating range, fully ESD protected.
