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, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
To ensure stable operation with a high-impedance output load, ROHM recommends adding a 10nF to 100nF capacitor in parallel with the output load to reduce oscillation and improve stability.
The maximum allowed voltage on the EN (enable) pin is 6V, which is higher than the recommended operating voltage of 5V. However, it's essential to ensure that the EN pin voltage does not exceed the supply voltage (VIN) to prevent damage to the device.
While the R6006KNX is rated for operation up to 105°C, ROHM recommends derating the output current and power dissipation to ensure reliable operation in high-temperature environments. Consult the datasheet and ROHM's application notes for specific guidance.
To minimize EMI, ROHM recommends using a shielded inductor, placing the R6006KNX close to the input capacitors, and using a ground plane or shielded layer on the PCB. Additionally, ensure that the output voltage is properly filtered and decoupled.
