TLC7701QPWREP datasheet by Texas Instruments

TLC7701QPWREP Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC7701QPWREP?
  The recommended operating voltage range for TLC7701QPWREP is 2.7V to 5.5V, although it can operate down to 2.3V with reduced performance.
• How do I ensure reliable operation of TLC7701QPWREP in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to derate the output current and voltage according to the thermal derating curve provided in the datasheet, and to ensure good thermal dissipation through proper PCB design and heat sinking.
• What is the maximum output current that TLC7701QPWREP can handle?
  The maximum output current that TLC7701QPWREP can handle is 50mA per channel, although it is recommended to limit the output current to 20mA per channel for reliable operation.
• How do I program the TLC7701QPWREP to output a specific voltage?
  The TLC7701QPWREP can be programmed to output a specific voltage by connecting the VREF pin to a resistive divider network that sets the desired output voltage, and by using the EN/UVLO pin to enable or disable the output.
• What is the purpose of the EN/UVLO pin on TLC7701QPWREP?
  The EN/UVLO pin on TLC7701QPWREP is used to enable or disable the output, and also provides undervoltage lockout (UVLO) protection, which disables the output when the input voltage falls below a certain threshold.
