BD9739KN-E2 Frequently Asked Questions (FAQ)
-
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, as well as the suggested PCB layout. Additionally, the input voltage should be within the recommended range, and the output load should be within the specified current rating.
-
The maximum junction temperature (Tj) for the BD9739KN-E2 is 150°C. Operating the device above this temperature can lead to reduced reliability and lifespan.
-
While the BD9739KN-E2 can operate up to 150°C, it's essential to consider the derating curves and thermal management when operating in high-temperature environments. ROHM recommends consulting the datasheet and application notes for guidance on high-temperature operation.
-
To protect the device from overcurrent and overvoltage conditions, it's recommended to add external protection circuits, such as overcurrent protection (OCP) and overvoltage protection (OVP) circuits, as well as input and output capacitors to filter out noise and transients.
