TPS60312DGSR datasheet by Texas Instruments

TPS60312DGSR Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value and type for the TPS60312DGSR?
  The recommended input capacitor value is 1uF to 10uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize noise.
• How do I ensure the TPS60312DGSR operates within its specified temperature range?
  Ensure good thermal design and layout practices, such as providing adequate heat sinking, using thermal vias, and keeping the device away from heat sources. Also, consider using a thermal pad or heat sink to dissipate heat.
• What is the maximum output current I can draw from the TPS60312DGSR?
  The maximum output current is 150mA, but it's recommended to derate the output current based on the ambient temperature and the device's thermal design to ensure reliable operation.
• Can I use the TPS60312DGSR in a battery-powered device?
  Yes, the TPS60312DGSR is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5uA, which helps to extend battery life. However, ensure the input voltage is within the recommended range and the device is properly bypassed to minimize noise and ripple.
• How do I layout the PCB to minimize noise and ensure stable operation of the TPS60312DGSR?
  Follow good PCB layout practices, such as separating the input and output sections, using a solid ground plane, and keeping the feedback network short and direct. Also, ensure the input and output capacitors are placed close to the device and connected with short, wide traces.
