TPS5405 Evaluation Module



Texas Instruments  TPS5405EVM

The TPS5405 is designed to provide fixed 5-V output and 2-A continuous current with an operational range of 6.5 V to 28 V and an external set switching frequency ranging from 50 kHz to 1.1 MHz.
  • Fixed 5-V Output
  • 6.5-V to 28-V Wide Input Voltage Range
  • Up to 2-A Maximum Continuous Output Loading Current
  • Pulse Skipping Mode to Achieve High Light Load Efficiency
  • Over 80% Efficiency at 10-mA Loading
  • Adjustable 50-kHz to 1.1-MHz Switching Frequency
    • Set by an External Resistor (Leave pin ROSC floating. Set frequency to 120 kHz and ground connection to 70 kHz)
  • Peak Current-Mode Control
  • Cycle-by-Cycle Over Current Protection
  • Switching Node Anti-Ringing to Ease EMI Issue
  • External Soft Start
