TPS70102PWPRG4 datasheet by Texas Instruments

TPS70102PWPRG4 Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value and type for the TPS70102PWPRG4?
  A 1-10uF ceramic capacitor (X5R or X7R dielectric) is recommended for input decoupling, placed as close to the VIN pin as possible.
• How do I ensure stability and prevent oscillations in the TPS70102PWPRG4?
  Ensure that the output capacitor is properly sized and placed, and that the feedback network is correctly configured. Also, add a 1-10nF capacitor in parallel with the feedback resistors to improve stability.
• What is the maximum output current capability of the TPS70102PWPRG4?
  The TPS70102PWPRG4 can deliver up to 2A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions. Consult the datasheet for specific current limits and thermal derating.
• Can I use the TPS70102PWPRG4 in a high-temperature environment?
  The TPS70102PWPRG4 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Ensure proper thermal design and consider derating the output current and voltage to ensure reliable operation.
• How do I configure the enable pin (EN) for proper operation?
  The EN pin is active-high, so connect it to a logic high (e.g., VCC) to enable the regulator. When EN is low, the regulator is in shutdown mode, and the output is disconnected from the input.
