TPS2066AD datasheet by Texas Instruments

TPS2066AD Frequently Asked Questions (FAQs)

• What is the maximum capacitive load that the TPS2066AD can handle?
  The TPS2066AD can handle a maximum capacitive load of 10,000 μF. However, it's recommended to limit the capacitive load to 4,700 μF to ensure stable operation.
• How do I ensure that the TPS2066AD switches on and off quickly?
  To ensure fast switching, make sure to use a low-ESR output capacitor (less than 10 mΩ) and minimize the PCB trace inductance. Additionally, use a pull-up resistor on the EN pin to ensure a fast rise time.
• What is the minimum input voltage required for the TPS2066AD to operate?
  The TPS2066AD can operate with an input voltage as low as 2.7 V, but it's recommended to use a minimum input voltage of 3.0 V to ensure reliable operation.
• Can I use the TPS2066AD in a high-temperature environment?
  The TPS2066AD is rated for operation up to 85°C, but it's recommended to derate the output current by 1.5 mA/°C above 70°C to ensure reliable operation.
• How do I prevent the TPS2066AD from overheating?
  To prevent overheating, ensure good thermal conduction between the device and the PCB, use a heat sink if necessary, and avoid operating the device at high ambient temperatures or with high output currents.
