TPS2021IDRQ1 datasheet by Texas Instruments

TPS2021IDRQ1 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2021IDRQ1?
  The maximum input voltage that can be applied to the TPS2021IDRQ1 is 5.5V, although the recommended operating input voltage range is 2.7V to 5.5V.
• How do I ensure the TPS2021IDRQ1 is properly powered up and initialized?
  To ensure proper power-up and initialization, make sure to follow the power-up sequencing guidelines in the datasheet, and provide a stable input voltage and clock signal. Also, ensure that the EN pin is properly driven to enable the device.
• What is the purpose of the EN pin, and how should it be driven?
  The EN (Enable) pin is used to enable or disable the TPS2021IDRQ1. It should be driven high (logic 1) to enable the device and low (logic 0) to disable it. The EN pin should be driven by a logic signal from a microcontroller or other digital source.
• How do I configure the TPS2021IDRQ1 for different output voltage settings?
  The TPS2021IDRQ1 has a fixed output voltage of 1.2V, 1.5V, or 1.8V, depending on the specific device variant. To configure the output voltage, select the appropriate device variant or use an external resistor divider network to set the output voltage.
• What is the typical output current capability of the TPS2021IDRQ1?
  The TPS2021IDRQ1 is capable of delivering up to 2A of output current, although the actual output current capability may vary depending on the input voltage, output voltage, and ambient temperature.
