TPS2110PW datasheet by Texas Instruments

TPS2110PW Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the output of the TPS2110PW?
  The maximum current that can be drawn from the output of the TPS2110PW is 1.5A per channel, but it's recommended to limit the current to 1A per channel for optimal performance and thermal considerations.
• How do I ensure that the TPS2110PW switches between channels correctly?
  To ensure correct channel switching, make sure to follow the recommended switching sequence and timing in the datasheet, and use a suitable logic signal to control the channel select pins (SEL0 and SEL1).
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the entire device. When EN is low, the device is in shutdown mode and draws minimal current. To use the EN pin, connect it to a logic signal that is high when the device is needed and low when it's not needed.
• How do I handle thermal considerations when using the TPS2110PW?
  To handle thermal considerations, 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.
• What is the recommended input capacitor value and type for the TPS2110PW?
  The recommended input capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor (e.g., X5R or X7R) to minimize voltage ripple and ensure stable operation.
