TPS61045DRBT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS61045DRBT involves placing the input and output capacitors close to the device, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • Choose input capacitors with a voltage rating higher than the maximum input voltage, and output capacitors with a voltage rating higher than the output voltage. X5R or X7R ceramic capacitors are recommended for their low ESR and high ripple current capability.
  • The TPS61045DRBT can operate in an ambient temperature range of -40°C to 125°C. However, the device's junction temperature should not exceed 150°C.
  • The output voltage of the TPS61045DRBT can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.21V), and R1 and R2 are the resistors in the feedback network.
  • The maximum input voltage for the TPS61045DRBT is 18V. Exceeding this voltage may damage the device.
