LTM4700IY Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pads away from high-frequency signals and ensure good thermal conduction to the heat sink.
  • Use a combination of capacitors with different ESR values to filter out high-frequency noise. A 10uF ceramic capacitor in parallel with a 100uF electrolytic capacitor is a good starting point. Optimize the filter design using simulation tools like LTspice.
  • The maximum input voltage is 15V, but it's recommended to derate the input voltage to 13.5V to ensure reliable operation and minimize the risk of overvoltage damage.
  • Use a soft-start circuit to limit the inrush current during start-up. Add a capacitor in series with the EN pin to slow down the turn-on time. For shutdown, use a voltage supervisor to ensure a clean shutdown sequence.
  • Use a heatsink with a thermal resistance of 2°C/W or lower. Ensure good thermal contact between the IC and the heatsink using a thermal interface material. A 1-inch square heatsink with a thickness of 0.5 inches is a good starting point.
