Description:Switching Voltage Regulators 4-V to 18-V input, 20-A synchronous SWIFT™ step-down power module with extended temperature 25-B3QFN -40 to 125
Texas Instruments provides a recommended PCB layout for the TPSM843B22RDGR-ET in the datasheet, but it's also recommended to follow general guidelines for thermal design, such as using a solid ground plane, placing thermal vias under the device, and using a thermal pad on the bottom of the device.
To ensure proper soldering, follow the recommended soldering profile provided in the datasheet, and use a solder with a melting point below 260°C. Also, make sure to use a soldering iron with a temperature control and a fine tip to avoid overheating the device.
The maximum allowed voltage deviation on the input pins is typically ±10% of the nominal input voltage, but it's recommended to check the specific application notes and datasheet for the TPSM843B22RDGR-ET for more information.
To handle EMI and noise issues, use proper PCB layout techniques, such as separating analog and digital grounds, using shielding, and placing bypass capacitors close to the device. Additionally, consider using EMI filters or common-mode chokes on the input and output lines.
The recommended input capacitor value and type depend on the specific application and input voltage. As a general rule, use a low-ESR capacitor with a value between 10uF to 100uF, and consider using a ceramic or film capacitor with a voltage rating above the maximum input voltage.
