ROHM recommends a thermal pad size of 2.5mm x 2.5mm with a minimum of 10 thermal vias (0.3mm diameter) to achieve optimal thermal performance. Additionally, a solid copper plane on the bottom layer can help to dissipate heat efficiently.
To ensure stable operation with a high-impedance input source, ROHM recommends adding a 1kΩ to 10kΩ resistor in series with the input pin to reduce the impedance and prevent oscillation.
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may cause damage to the device. It's recommended to use a voltage limiter or a resistor divider network to ensure the EN pin voltage remains within the specified range.
While the BD7LS17G-CTL is rated for operation up to 125°C, ROHM recommends derating the output current and voltage to ensure reliable operation in high-temperature environments. Consult the datasheet and ROHM's application notes for specific guidance.
To troubleshoot output voltage instability or oscillation issues, check the PCB layout for proper thermal design, ensure the input voltage is within the specified range, and verify that the output capacitor is of sufficient value and type. Additionally, check for any noise or ripple on the input voltage and ensure the device is not overheating.
