TPS2223ADB datasheet by Texas Instruments

TPS2223ADB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2223ADB?
  The maximum input voltage that can be applied to the TPS2223ADB is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I ensure the TPS2223ADB 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 time.
• What is the minimum input voltage required for the TPS2223ADB to operate?
  The minimum input voltage required for the TPS2223ADB to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS2223ADB as a high-side switch?
  No, the TPS2223ADB is a low-side switch, meaning it can only switch the ground connection of a load. It's not suitable for high-side switching applications.
• How do I calculate the power dissipation of the TPS2223ADB?
  To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout x Rds(on), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Rds(on) is the on-state resistance of the switch.
