TPS61028DRCR datasheet by Texas Instruments

TPS61028DRCR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS61028DRCR?
  The maximum input voltage that can be applied to the TPS61028DRCR is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
• How do I ensure the stability of the output voltage?
  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 10uF ceramic capacitor is recommended.
• What is the minimum input capacitance required for the TPS61028DRCR?
  The minimum input capacitance required for the TPS61028DRCR is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stable operation.
• Can I use the TPS61028DRCR in a high-temperature environment?
  The TPS61028DRCR is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
• How do I calculate the output voltage of the TPS61028DRCR?
  The output voltage of the TPS61028DRCR can be calculated using the formula: Vout = 1.21V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
