BD49101ARFS-ME2 Frequently Asked Questions (FAQs)
-
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 overall ESR. Additionally, the output capacitor should be placed as close as possible to the IC.
-
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the internal circuitry. It is recommended to use a voltage divider or a clamp circuit to limit the voltage on the EN pin.
-
The BD49101ARFS-ME2 is rated for operation up to 105°C. However, the device's performance and reliability may degrade at high temperatures. ROHM recommends derating the output current and voltage according to the temperature derating curve provided in the datasheet.
-
To troubleshoot oscillations or instability issues, ROHM recommends checking the PCB layout for any noise or signal integrity issues, ensuring that the input and output capacitors are properly selected and placed, and verifying that the feedback network is correctly implemented. Additionally, reducing the output voltage or current may help to stabilize the operation.
