TPS2390DGKR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the TPS2390DGKR. TI recommends a 4-layer PCB with a solid ground plane, and the device should be placed close to the power source. Decoupling capacitors should be placed as close as possible to the device pins. A detailed layout guide can be found in the TI application note SLVA883.
  • The sense resistor value depends on the current sensing range and the desired accuracy. TI provides a sense resistor calculator tool to help with the selection. A general rule of thumb is to choose a sense resistor value that results in a voltage drop between 10mV to 100mV at the maximum expected current.
  • The maximum allowed voltage on the SENSE pin is 2.5V. Exceeding this voltage can damage the device. It's essential to ensure that the voltage across the sense resistor does not exceed 2.5V, even during fault conditions.
  • Inrush current can be handled by adding a soft-start circuit or a current limiter to the power supply. The TPS2390DGKR has a built-in current limit feature, but it may not be sufficient for all applications. A detailed analysis of the startup sequence and inrush current is necessary to ensure reliable operation.
  • The EN (enable) pin is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. The EN pin can be used to implement power sequencing, reduce standby power consumption, or provide a shutdown function.
