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.
To ensure stable output voltage regulation, it is recommended to use a high-quality output capacitor with low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Additionally, the input capacitor should be placed close to the VIN pin to reduce noise.
Although the datasheet specifies a maximum input voltage of 18V, it is recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the device.
The BD9300F-E2 has a built-in overcurrent protection (OCP) feature that limits the output current to 2.5A. However, it is still recommended to add an external fuse or PTC (Positive Temperature Coefficient) thermistor to protect the device from excessive current surges.
Although the datasheet specifies an operating temperature range of -40°C to 105°C, it is recommended to operate the device within a range of -20°C to 85°C for optimal performance and reliability.
