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 output voltage regulation, it's essential to follow the recommended input and output capacitor values and types, as well as the suggested PCB layout. Additionally, the input voltage should be within the recommended range, and the output load should not exceed the maximum rated current.
The maximum allowed input voltage ripple for the R6515ENX is 1Vp-p. Exceeding this value may affect the regulator's performance and stability.
The R6515ENX is rated for operation up to 105°C, but it's essential to consider the derating curves for output current and power dissipation at high temperatures. Additionally, the device should be mounted on a PCB with a suitable thermal design to ensure reliable operation.
The R6515ENX has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, it's still recommended to add external protection components, such as fuses or PTC resistors, to prevent damage from excessive current or voltage surges.
