TPS61085PWG4 datasheet by Texas Instruments

TPS61085PWG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS61085PWG4?
  The maximum input voltage that can be applied to the TPS61085PWG4 is 12V, but it's recommended to keep it below 10V to ensure reliable operation and to prevent damage to the internal components.
• How do I optimize the layout of the TPS61085PWG4 to minimize EMI?
  To minimize EMI, it's recommended to follow a star-grounding configuration, keep the input and output capacitors close to the device, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW pin) away from sensitive nodes.
• What is the recommended input capacitor type and value for the TPS61085PWG4?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be rated for at least 16V and have a temperature rating of X5R or X7R.
• How do I calculate the output voltage of the TPS61085PWG4?
  The output voltage of the TPS61085PWG4 can be calculated using the following formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.21V), R1 is the feedback resistor, and R2 is the divider resistor.
• What is the maximum output current that the TPS61085PWG4 can deliver?
  The maximum output current that the TPS61085PWG4 can deliver is 2A, but it's recommended to keep the output current below 1.5A to ensure reliable operation and to prevent overheating.
