ROHM provides a recommended PCB layout in their application note AN1191, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The selection of input and output capacitors depends on the specific application requirements. ROHM recommends using low-ESR capacitors with a capacitance value of 10uF to 22uF for the input and output. The capacitor selection guide in the datasheet provides more information on how to choose the correct capacitors.
The BA2902YFV-CE2 is rated for operation up to 85°C ambient temperature. However, it's recommended to derate the output current and voltage according to the thermal derating curve in the datasheet to ensure reliable operation.
ROHM recommends using overvoltage protection (OVP) and undervoltage lockout (UVLO) circuits to protect the device from voltage transients and faults. The application note AN1191 provides more information on how to implement these protection circuits.
ROHM recommends a soldering temperature of 260°C (max) and a soldering time of 10 seconds (max) to prevent damage to the device. It's also recommended to follow the soldering profile in the datasheet to ensure reliable assembly.
