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 to reduce thermal resistance.
To ensure stable operation with a high-capacitance output capacitor, ROHM recommends adding a 1-10nF ceramic capacitor in parallel with the output capacitor to reduce the risk of oscillation. Additionally, the output capacitor's ESR should be less than 100mΩ to prevent oscillation.
Although the datasheet doesn't specify a maximum voltage for the EN pin, ROHM recommends keeping the voltage on the EN pin within the range of 0 to VCC (5V) to ensure proper operation and prevent damage to the device.
While the BD22441G-CTR is rated for operation up to 105°C, ROHM recommends derating the output current and voltage to ensure reliable operation in high-temperature environments. Consult ROHM's application notes for specific derating guidelines.
To troubleshoot oscillation or instability issues, check the PCB layout for proper thermal design, ensure the output capacitor is properly sized and has a low ESR, and verify that the input voltage is within the recommended range. Also, check for any noise or ripple on the input voltage and ensure that the device is not overheating.
