A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and wide, and use thermal vias to dissipate heat. Refer to the TI application note 'TPS23753PWR PCB Layout Guidelines' for more information.
Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-10 μH). Consider the inductor's physical size, core material, and operating frequency. TI's 'TPS23753PWR Inductor Selection Guide' can help with the selection process.
The maximum ambient temperature for the TPS23753PWR is 85°C. However, the device can operate up to 105°C with derating. Refer to the datasheet for thermal derating curves and guidelines for high-temperature operation.
Yes, the TPS23753PWR can be used in a redundant power supply configuration. However, additional external circuitry and control logic are required to ensure proper operation and fault detection. Consult TI's application notes and design guides for more information.
Use an oscilloscope to monitor the output voltage, input voltage, and current sense signals. Check for proper PCB layout, component selection, and thermal design. Consult the datasheet, application notes, and TI's support resources for troubleshooting guides and FAQs.
