Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as using a solid ground plane, minimizing trace lengths, and keeping the input and output capacitors close to the device.
The TPSM843A26RDGR is rated for operation from -40°C to 125°C. Ensure proper thermal management by providing adequate heat sinking, using thermal vias, and keeping the device away from heat sources. Monitor the device's temperature using the thermal monitoring pin (TMP) if necessary.
The TPSM843A26RDGR has an absolute maximum input voltage rating of 26V. However, the recommended operating input voltage range is 3.5V to 20V. Exceeding the maximum rating can damage the device.
The output capacitor value and type depend on the specific application requirements. A general guideline is to use a low-ESR ceramic capacitor with a value between 10uF to 22uF. Consult the datasheet and application notes for more information on capacitor selection.
The TPSM843A26RDGR has a soft-start feature that limits the inrush current during startup. During shutdown, the device enters a low-power state, and the output voltage decays to zero. The device can be shut down by pulling the EN pin low or by removing the input voltage.
