BD677G Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern around the device.
  • Use a capacitor with an ESR of 0.1 ohm or less, and add a 1-2 ohm resistor in series with the capacitor to dampen oscillations.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
  • Yes, but ensure the device is derated according to the thermal derating curve in the datasheet. The maximum junction temperature is 150°C.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and add a common-mode choke or ferrite bead to the output.
