ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
To ensure stable operation with a high-ESR output capacitor, ROHM recommends adding a 1nF to 10nF ceramic capacitor in parallel with the output capacitor to reduce the ESR. Additionally, the output capacitor should be placed close to the IC to minimize parasitic inductance.
The maximum allowed voltage on the EN pin is 6V, which is higher than the recommended operating voltage of 5V. However, it's essential to ensure that the EN pin voltage does not exceed the IC's supply voltage (VIN) to prevent damage.
The BD6226FP-E2 is rated for operation up to 105°C, but ROHM recommends derating the output current and power dissipation to ensure reliable operation. Consult the datasheet for specific derating guidelines and consider using a heat sink or thermal management solution if necessary.
To troubleshoot oscillations or instability issues, ROHM recommends checking the PCB layout for parasitic inductance and capacitance, ensuring proper decoupling of the input and output capacitors, and verifying that the output capacitor meets the recommended specifications. Additionally, check for noise on the VIN and EN pins, and ensure that the IC is properly grounded.
