TPS65640RHRR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS65640RHRR evaluation module documentation, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The output capacitor selection depends on the output voltage, current, and ripple requirements. TI recommends using a low-ESR capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. The capacitor should also be placed close to the output pins to minimize inductance.
  • Although the datasheet specifies a maximum input voltage of 5.5V, TI recommends limiting the input voltage to 5V to ensure reliable operation and prevent damage to the device.
  • The TPS65640RHRR has built-in OCP and SCP features. To implement these features, connect the OCP pin to a resistor divider network that sets the current limit, and connect the SCP pin to a capacitor that sets the short-circuit detection time. Refer to the datasheet and application notes for detailed implementation guidelines.
  • The thermal derating curve is not explicitly provided in the datasheet. However, TI recommends following the thermal design guidelines in the datasheet and application notes to ensure the device operates within the specified temperature range. A general rule of thumb is to derate the output current by 1% per degree Celsius above 25°C.
