TPS3619-33DGKRG4 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for power management ICs, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.
  • The output voltage tolerance of the TPS3619-33DGKRG4 is typically ±2% over the entire operating temperature range. To calculate the output voltage tolerance, you can use the formula: Output Voltage Tolerance = (Output Voltage x Tolerance Percentage) / 100. For example, if the output voltage is 3.3V and the tolerance percentage is 2%, the output voltage tolerance would be ±66mV.
  • The maximum input voltage that the TPS3619-33DGKRG4 can handle is 6.5V. Exceeding this voltage can cause damage to the device. It's recommended to use a voltage regulator or other protection circuitry to ensure that the input voltage remains within the specified range.
  • The TPS3619-33DGKRG4 has a built-in overvoltage protection (OVP) feature that can be enabled by connecting the OVP pin to a voltage source. When the output voltage exceeds the OVP threshold (typically 3.9V), the device will shut down to prevent damage. You can also implement external OVP circuitry using a voltage comparator and a switch to disconnect the input power supply in case of an overvoltage condition.
  • The thermal shutdown temperature of the TPS3619-33DGKRG4 is typically 150°C. When the device temperature exceeds this threshold, it will shut down to prevent damage. The device will automatically restart when the temperature drops below 130°C.
