TPS2090DR datasheet by Texas Instruments

TPS2090DR Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced by the TPS2090DR?
  The TPS2090DR can source up to 1.5A of current per channel, but it's recommended to limit it to 1A per channel for reliable operation.
• How do I ensure that the TPS2090DR switches between channels correctly?
  To ensure correct channel switching, make sure to follow the recommended switching sequence in the datasheet, and use a clock signal with a frequency between 10 kHz and 100 kHz.
• What is the minimum input voltage required for the TPS2090DR to operate?
  The TPS2090DR requires a minimum input voltage of 2.7V to operate, but it's recommended to use a minimum of 3V for reliable operation.
• Can I use the TPS2090DR with a 5V power supply?
  Yes, the TPS2090DR can be used with a 5V power supply, but you'll need to ensure that the input voltage to the device does not exceed 5.5V to prevent damage.
• How do I handle thermal issues with the TPS2090DR?
  To handle thermal issues, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and follow the recommended layout and thermal design guidelines in the datasheet.
