TPS61021DSGR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS61021DSGR is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
  • To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A minimum capacitance value of 10uF is recommended, and the ESR should be less than 1 ohm.
  • The minimum input capacitance required for the TPS61021DSGR is 1uF, but it's recommended to use a higher capacitance value, such as 4.7uF or 10uF, to ensure stable operation and to filter out noise and ripple.
  • The TPS61021DSGR is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage to ensure reliable operation at high temperatures. It's also essential to ensure good thermal design and heat dissipation to prevent overheating.
  • The output voltage of the TPS61021DSGR can be calculated using the following formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.21V), and R1 and R2 are the resistors used to set the output voltage.
