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
