RI-TMS3705ADR datasheet by Texas Instruments

RI-TMS3705ADR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the RI-TMS3705ADR to ensure optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the center of the board, and the input and output capacitors should be placed as close to the device as possible.
• How do I ensure the stability of the output voltage in the RI-TMS3705ADR?
  To ensure stability, the output voltage should be decoupled with a capacitor (e.g., 10uF) and a resistor (e.g., 10Ω) in series. Additionally, the input voltage should be well-regulated and the output should not be overloaded.
• What is the maximum input voltage that the RI-TMS3705ADR can handle?
  The maximum input voltage is 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
• How do I calculate the output voltage of the RI-TMS3705ADR?
  The output voltage can be calculated using the formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the internal reference voltage (1.25V).
• What is the maximum output current that the RI-TMS3705ADR can deliver?
  The maximum output current is 3.5A, but it's recommended to keep the output current below 3A to ensure reliable operation and to prevent overheating.
