ROHM recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer, and multiple vias to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure reliable operation in high-temperature environments, it's essential to follow the recommended derating curves, ensure good thermal design, and consider using a heat sink or thermal interface material if necessary.
Although the datasheet specifies a maximum input voltage of 40V, it's recommended to limit the input voltage to 36V to ensure reliable operation and prevent damage to the device.
While the RB162L-40TE25 is capable of delivering up to 1A of output current, it's essential to consider the thermal design and ensure that the device is properly cooled to prevent overheating. ROHM recommends using a heat sink or thermal interface material for high-current applications.
To minimize noise and ripple on the output voltage, use a high-quality output capacitor with low ESR, ensure good PCB layout and decoupling, and consider adding a noise filter or LC filter if necessary.
