TPS61040DDCR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS61040DDCR 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. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor has a low equivalent series resistance (ESR) and is placed close to the device. Also, avoid using ceramic capacitors with high ESR values.
  • The TPS61040DDCR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The TPS61040DDCR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.
  • The output voltage of the TPS61040DDCR can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the feedback resistors, Vin is the input voltage, and Vref is the internal reference voltage (1.21V).
