BD9300FV-E2 - ROHM Semiconductor

BD9300FV-E2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer, and multiple vias to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
• How do I ensure stable output voltage regulation with the BD9300FV-E2?
  To ensure stable output voltage regulation, it is recommended to use a high-quality output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value (e.g., 10uF or higher). Additionally, the input capacitor should be placed close to the VIN pin to reduce noise and ripple.
• What is the maximum ambient temperature for reliable operation?
  The BD9300FV-E2 is rated for operation up to 105°C ambient temperature, but it is recommended to derate the output current and voltage to ensure reliable operation above 85°C.
• How do I protect the BD9300FV-E2 from overvoltage and undervoltage conditions?
  It is recommended to use an external overvoltage protection (OVP) circuit and an undervoltage lockout (UVLO) circuit to protect the BD9300FV-E2 from voltage transients and faults. ROHM provides a reference design for OVP and UVLO circuits in the application note.
• What is the recommended input capacitor type and value for the BD9300FV-E2?
  ROHM recommends using a ceramic capacitor with a value of 1uF to 10uF and a voltage rating of 10V or higher. The input capacitor should be placed close to the VIN pin to reduce noise and ripple.
