TPSM82903SISR Frequently Asked Questions (FAQs)

  • TI recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to improve heat dissipation.
  • Use a high-quality input capacitor (e.g., X5R or X7R ceramic) with a minimum capacitance of 10uF, and consider adding a feedforward capacitor (e.g., 100nF) to improve transient response.
  • The maximum output current is 3A, but it's recommended to derate the output current to 2.5A for optimal reliability and thermal performance.
  • Use an external OCP circuit, such as a sense resistor and a comparator, to monitor the output current and trigger a shutdown signal to the EN pin in case of an overcurrent event.
  • Use a high-quality, low-ESR input capacitor (e.g., X5R or X7R ceramic) with a minimum capacitance of 10uF and a maximum ESR of 100mΩ.
