TPS65021RHAT datasheet by Texas Instruments

TPS65021RHAT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS65021RHAT can handle?
  The TPS65021RHAT can handle a maximum input voltage of 18V, but it's recommended to operate within the 6V to 14V range for optimal performance.
• How do I configure the TPS65021RHAT for a specific output voltage?
  The TPS65021RHAT output voltage can be configured by connecting resistors R1 and R2 between the FB pin and the output voltage pin. The ratio of R1 to R2 determines the output voltage. Refer to the datasheet for the calculation formula.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. Connect EN to a logic high signal to enable the device, or connect it to a logic low signal to disable it.
• How do I ensure the TPS65021RHAT operates within a safe temperature range?
  The TPS65021RHAT has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. Ensure good thermal design and heat dissipation to keep the device within a safe temperature range.
• What is the minimum input capacitance required for the TPS65021RHAT?
  The minimum input capacitance required for the TPS65021RHAT is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.
