DRV603PWR datasheet by Texas Instruments

DRV603PWR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of DRV603PWR?
  The maximum power dissipation of DRV603PWR is 2.5W. However, it's recommended to keep the junction temperature (TJ) below 150°C to ensure reliable operation.
• How do I choose the right inductor value for my application?
  The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet or use TI's WEBENCH Power Designer tool to find the optimal inductor value.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. You can use the EN pin to implement power sequencing or to turn off the device when not in use.
• How do I ensure the stability of the output voltage?
  To ensure output voltage stability, make sure to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. Also, ensure that the output voltage is within the recommended range of 0.9V to 5.5V.
• What is the recommended PCB layout for DRV603PWR?
  A good PCB layout for DRV603PWR involves keeping the high-current paths short and wide, using a solid ground plane, and placing the input and output capacitors close to the device. Refer to the datasheet or TI's application notes for more detailed layout guidelines.
