TPS3123J18DBVT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
  • To ensure stability, make sure to follow the recommended component values and layout guidelines, and also consider the output capacitor's ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) when selecting the output capacitor. Additionally, a minimum output capacitance of 10uF is recommended.
  • While the datasheet specifies a maximum input voltage of 18V, it's recommended to derate the input voltage to 15V or lower to ensure reliable operation and to prevent damage to the IC.
  • The TPS3123J18DBVT is rated for operation up to 125°C, but it's essential to consider the IC's power dissipation and thermal management when operating in high-temperature environments. Ensure proper heat sinking and thermal design to prevent overheating.
  • The output voltage of the TPS3123J18DBVT is set by the resistive divider network consisting of R1 and R2. The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R2/R1).
