LM3464MH/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the IC to improve thermal performance. A good layout should also minimize the distance between the IC and the output capacitors.
  • The output capacitors should have a low ESR (Equivalent Series Resistance) and be able to handle the output current. A minimum capacitance of 10uF is recommended, but larger values can be used for improved transient response. X5R or X7R ceramic capacitors are good options.
  • The absolute maximum input voltage rating is 42V, but it's recommended to operate the device within the recommended input voltage range of 7V to 40V for optimal performance and reliability.
  • The LM3464MH/NOPB is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
  • The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. The device's thermal resistance (θJA) should also be considered when calculating the junction temperature.
