L5991D013TR Frequently Asked Questions (FAQs)

  • A good PCB layout for the L5991D013TR should include a solid ground plane, wide power traces, and a thermal relief pattern under the IC to facilitate heat dissipation. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure reliable start-up and shutdown, make sure to follow the recommended power-up and power-down sequences outlined in the datasheet. Also, ensure that the input voltage rises and falls monotonically, and that the input voltage is stable before enabling the device.
  • When selecting external components, consider the input and output capacitors, inductor, and diode. Choose components with low ESR, high ripple current rating, and suitable voltage ratings. The inductor should have a high saturation current rating and low DCR.
  • To optimize the device for low standby power consumption, ensure that the device is in shutdown mode when not in use. Also, consider using a low-quiescent-current voltage regulator for the bias supply, and minimize the number of external components to reduce standby power consumption.
  • For EMI filtering and shielding, consider using a common-mode choke, X-capacitors, and Y-capacitors to filter out conducted emissions. Use a shielded enclosure and ensure good grounding practices to minimize radiated emissions.
