BQ24721CRHBR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The input and output capacitors should be placed close to the IC, and the high-current paths should be kept short and wide to minimize resistance and inductance.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value based on the output voltage and current requirements. A shielded inductor is recommended to reduce EMI.
  • The BQ24721CRHBR is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system.
  • The BQ24721CRHBR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values should be chosen based on the desired overcurrent threshold and the input voltage.
  • Yes, the BQ24721CRHBR can be used in a synchronous rectification configuration to improve efficiency. However, this requires additional external components and careful design to ensure proper operation.
