TPS3619-33DGKG4 Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS3619-33DGKG4 should prioritize minimizing the loop area of the power and ground traces to reduce electromagnetic interference (EMI). Place the input and output capacitors close to the device, and use a solid ground plane to reduce noise. Refer to the Texas Instruments application note 'TPS3619 PCB Layout Guidelines' for more information.
  • Choose input capacitors with a low equivalent series resistance (ESR) and a high ripple current rating to minimize voltage drops and ensure stable operation. For output capacitors, select ones with a low ESR and a high capacitance to filter out noise and ripple. Refer to the datasheet for recommended capacitor values and types.
  • The TPS3619-33DGKG4 is rated for operation from -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures. Ensure proper thermal management and heat sinking to maintain a safe operating temperature.
  • To ensure proper power-up and power-down sequencing, connect the enable pin (EN) to a logic-level signal that is high during normal operation and low during shutdown. Use a soft-start circuit or a power-up sequencing controller to ensure a controlled voltage ramp-up and to prevent inrush currents.
  • To ensure EMC compliance, use a shielded enclosure, keep the device and its associated components away from sensitive circuits, and use a common-mode choke or ferrite bead to filter out high-frequency noise. Follow the guidelines in the IEC 61000-4-x series of standards for EMC testing and compliance.
