ROHM provides a recommended PCB layout in the application note AN11952, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The selection of input and output capacitors depends on the specific application requirements, such as voltage rating, capacitance value, and ESR. ROHM recommends using low-ESR capacitors with a voltage rating of at least 2x the input voltage, and a capacitance value of 10uF to 22uF for the input capacitor and 10uF to 47uF for the output capacitor.
The BA4584RF-E2 is rated for operation in an ambient temperature range of -40°C to +85°C, but it's recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet to ensure reliable operation.
ROHM provides guidelines for EMC compliance in the application note AN11952, which includes recommendations for PCB layout, component selection, and shielding to minimize EMI and ensure compliance with relevant EMC standards such as CISPR 22 and FCC Part 15.
ROHM recommends a soldering temperature of 260°C to 280°C and a soldering time of 3 seconds to 5 seconds to ensure reliable solder joints and prevent damage to the device.
