LTC2946MPMS-1#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC2946 involves keeping the high-frequency switching nodes (VIN, VOUT, and SW) away from sensitive analog nodes (SENSE+, SENSE-, and VCC). Use a solid ground plane, and keep the input and output capacitors close to the IC. A 4-layer board with a dedicated power plane is recommended.
  • To ensure accurate current sensing, use a low-impedance current sense resistor (RSENSE) and place it as close to the IC as possible. Use a Kelvin connection to the sense resistor to minimize parasitic resistance and inductance. Also, ensure that the sense lines are routed away from noisy signals and are not shared with other signals.
  • The maximum ambient temperature for the LTC2946 is 125°C. However, the device can operate up to 150°C with derating. Refer to the datasheet for thermal derating curves.
  • The LTC2946 is designed to operate with a stable input voltage. If the input voltage is not stable, it may affect the accuracy of the current measurement. However, the device can tolerate some input voltage ripple. If the input voltage is not stable, consider using a voltage regulator or a filter to stabilize the input voltage.
  • The power dissipation of the LTC2946 can be calculated using the following formula: PDISS = (VIN x IIN) + (VOUT x IOUT) + (VIN x ISW). Where VIN is the input voltage, IIN is the input current, VOUT is the output voltage, IOUT is the output current, and ISW is the switching current. Refer to the datasheet for more information.
