ROHM recommends a PCB layout with a thermal relief pattern under the IC, and a minimum of 2oz copper thickness to ensure good heat dissipation. A thermal via array under the IC can also be used to improve thermal performance.
To ensure the stability of the output voltage, it is recommended to use a capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. The output capacitor should be placed as close to the output pin as possible, and the PCB layout should be designed to minimize the loop inductance.
The maximum allowed input voltage ripple for the RQ6E080AJTCR is 10% of the input voltage. Exceeding this limit may affect the stability of the output voltage and the overall performance of the device.
The RQ6E080AJTCR is rated for operation up to 105°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and ensure good heat dissipation to ensure reliable operation in high-temperature environments.
The RQ6E080AJTCR has built-in overcurrent protection (OCP) and thermal shutdown (TSD) features. However, it is still recommended to add external protection components such as fuses or PTC thermistors to ensure the device is protected from excessive current and temperature.
