TPS70148PWPR datasheet by Texas Instruments

TPS70148PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS70148PWPR?
  The maximum input voltage that can be applied to the TPS70148PWPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a capacitor with a value between 1uF to 10uF on the output pin, and to keep the input capacitor value between 1uF to 10uF as well. Additionally, the PCB layout and component placement can affect stability, so it's crucial to follow good design practices.
• What is the maximum output current that the TPS70148PWPR can provide?
  The maximum output current that the TPS70148PWPR can provide is 1.5A, but it's recommended to keep it below 1A for optimal performance and to prevent overheating.
• How do I handle thermal considerations for the TPS70148PWPR?
  To handle thermal considerations, it's essential to provide adequate heat sinking, such as using a thermal pad or a heat sink, and to keep the device away from other heat sources. The maximum junction temperature is 150°C, and the device should be operated at a temperature below 125°C for optimal performance and reliability.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the device. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. This pin can be used to implement power sequencing or to turn the device on and off as needed.
