TPS2421-1DDAR Frequently Asked Questions (FAQ)

  • The maximum current rating of the TPS2421-1DDAR is 2.5A, but it can be limited by the thermal performance of the PCB and the ambient temperature.

  • Choose an input capacitor with a voltage rating that exceeds the maximum input voltage, and a capacitance value that is at least 10uF to ensure stability and low output voltage ripple.

  • The EN (enable) pin is used to turn the device on and off. When EN is high, the device is enabled, and when EN is low, the device is disabled and in a low-power state.

  • Ensure good thermal design practices, such as providing adequate heat sinking, using a thermally conductive PCB material, and keeping the device away from heat sources.

  • The TPS2421-1DDAR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure the device is properly heat-sinked and follow the recommended thermal design guidelines.
