TPS2045ADR Frequently Asked Questions (FAQs)

  • The maximum current rating of the TPS2045ADR is 4A, but it can be limited by the thermal performance of the PCB and the ambient temperature.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to place the capacitor close to the output pin.
  • The EN (enable) pin is used to turn the device on and off. To use it, connect the EN pin to a logic-level signal (e.g. from a microcontroller) to enable or disable the device. When EN is low, the device is in shutdown mode and consumes minimal power.
  • Choose an input capacitor with a voltage rating that exceeds the maximum input voltage, and a capacitance value that is at least 1uF. The capacitor should also have a low ESR to minimize voltage ripple.
  • The thermal derating of the TPS2045ADR is 1.5°C/W. This means that the device's power rating decreases as the ambient temperature increases. It is essential to consider thermal derating when designing the system to ensure reliable operation.
