Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good thermal design practices, such as using a solid ground plane, minimizing thermal resistance, and keeping the device away from heat sources.
The input capacitor selection depends on the input voltage, ripple current, and ESR requirements. TI recommends using a low-ESR capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the input voltage.
The output current derating for high ambient temperatures is not explicitly stated in the datasheet. However, according to TI's application notes, the maximum output current can be derated by 1.5% per degree Celsius above 50°C.
While the TPSM365R15FRDNR is a high-quality module, it's essential to evaluate its suitability for high-reliability or aerospace applications. TI provides additional documentation and support for these applications, including radiation reports and reliability data.
The enable pin is an active-high input. Ensure that the enable pin is properly biased and that the input voltage is within the recommended range. Also, check for any noise or ringing on the enable pin, as it can cause issues with the module's operation.
