TPS61021DSGT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS61021DSGT involves placing the input and output capacitors close to the IC, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • Choose input capacitors with a low ESR (Equivalent Series Resistance) and a high ripple current rating. For output capacitors, choose ones with a low ESR and a high capacitance value. The datasheet recommends a minimum capacitance value of 10uF for the input capacitor and 22uF for the output capacitor.
  • The maximum ambient temperature range for the TPS61021DSGT is -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures, so it's recommended to operate the device within a temperature range of -20°C to 85°C for optimal performance.
  • The output voltage of the TPS61021DSGT can be calculated using the following formula: Vout = Vfb * (1 + R1/R2), where Vfb is the feedback voltage (typically 0.8V), R1 is the resistance between the output and the feedback pin, and R2 is the resistance between the feedback pin and ground.
  • The maximum input voltage for the TPS61021DSGT is 18V. Exceeding this voltage may damage the device.
