TPS2226ADB datasheet by Texas Instruments

TPS2226ADB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2226ADB?
  The maximum input voltage that can be applied to the TPS2226ADB is 12V, but it's recommended to keep it below 10V for reliable operation.
• How do I ensure the TPS2226ADB switches on and off quickly?
  To ensure fast switching, make sure to use a low-ESR output capacitor, minimize the PCB trace inductance, and use a pull-up resistor on the enable pin (EN) to reduce the rise and fall times.
• Can I use the TPS2226ADB in a high-temperature environment?
  Yes, the TPS2226ADB is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
• How do I calculate the output voltage ripple of the TPS2226ADB?
  The output voltage ripple can be estimated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
• What is the recommended layout and placement for the TPS2226ADB?
  Keep the input and output capacitors close to the device, use a solid ground plane, and minimize the distance between the device and the output capacitor. Also, ensure that the high-current paths are short and wide to reduce losses.
