TPS2493PWR datasheet by Texas Instruments

TPS2493PWR Frequently Asked Questions (FAQs)

• What is the maximum current rating of the TPS2493PWR?
  The maximum current rating of the TPS2493PWR is 3A, but it can be limited by the thermal performance of the PCB and the ambient temperature.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the FB pin and the output voltage.
• 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 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 the EN pin is high, the device is enabled, and when it is low, the device is disabled.
• How do I adjust the output voltage?
  The output voltage can be adjusted by using a resistive divider network between the output voltage and the FB (feedback) pin. The ratio of the resistors determines the output voltage, and the recommended ratio is 1:1 for a 3.3V output and 2:1 for a 5V output.
• What is the thermal shutdown temperature of the TPS2493PWR?
  The thermal shutdown temperature of the TPS2493PWR is typically 150°C, and the device will shut down when the junction temperature exceeds this value.
