A good PCB layout for the TPS23882RTQR involves keeping the high-current paths short and wide, using a solid ground plane, and placing the input capacitors close to the device. TI provides a recommended layout in the datasheet and in application notes.
Choose input capacitors with a voltage rating that exceeds the maximum input voltage, and a capacitance value that meets the recommended range (e.g., 10-22 μF). Consider using low-ESR capacitors (e.g., X5R or X7R dielectrics) to minimize power losses.
The TPS23882RTQR supports cable lengths up to 100 meters, but this can vary depending on the specific application and cable characteristics. It's essential to consider the cable's capacitance, inductance, and resistance when designing the system.
The TPS23882RTQR has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the SENSE pin and the output, and set the overcurrent threshold by selecting the appropriate Rs value. The device will limit the output current to the set threshold during an overcurrent event.
Yes, the TPS23882RTQR can be used in a redundant power supply configuration. The device's ORing functionality allows multiple power supplies to be connected in parallel, ensuring that the output remains active even if one power supply fails.
