BD9P155EFV-CE2 Frequently Asked Questions (FAQs)

  • ROHM recommends a 2-layer or 4-layer PCB with a thermal relief pattern under the IC to improve heat dissipation. A minimum of 1 oz copper thickness is recommended for the PCB.
  • To ensure stable operation with a high-ESR output capacitor, add a 10nF to 22nF ceramic capacitor in parallel with the output capacitor to reduce the ESR effect.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the internal circuitry.
  • While the BD9P155EFV-CE2 is rated for operation up to 105°C, it's recommended to derate the output current and consider additional thermal design considerations for high-temperature applications.
  • To minimize EMI, use a shielded inductor, keep the switching node (SW) as short as possible, and add a 10nF to 22nF capacitor between the VIN and GND pins to reduce noise.
