STMicroelectronics provides a recommended PCB layout in the application note AN5273, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise and EMI.
The UPSD3434EB40U6 has a programmable output voltage feature that can be configured using the I2C interface. The device has a set of registers that allow the user to set the output voltage, and the datasheet provides a detailed description of the register settings and the corresponding output voltage values.
While the datasheet specifies a maximum input voltage of 40V, it's recommended to derate the input voltage to 36V to ensure reliable operation and to prevent damage to the device. Additionally, the input voltage should be within the specified range to ensure proper regulation and to prevent overvoltage protection (OVP) from triggering.
The UPSD3434EB40U6 has a built-in OCP feature that can be enabled by setting the OCP threshold using the I2C interface. The device also has a dedicated OCP pin that can be used to implement external OCP circuitry. The datasheet provides more information on how to implement OCP and the recommended settings for different applications.
The thermal derating curve for the UPSD3434EB40U6 is provided in the datasheet and shows the maximum output current that the device can deliver at different ambient temperatures. The curve is based on the device's junction temperature (Tj) and the maximum allowed temperature rise above the ambient temperature.
