STMicroelectronics provides a recommended PCB layout in the application note AN4391, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The input capacitor values depend on the input voltage, output voltage, and output current. A general guideline is to use a capacitor with a value between 10uF to 22uF, with a voltage rating of at least 1.5 times the input voltage. However, it's recommended to consult the application note AN4391 for more detailed guidance on capacitor selection.
The TEA3717DP is rated for operation up to 85°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation at high temperatures. Consult the datasheet and application note AN4391 for more information on thermal derating.
The TEA3717DP has built-in OVP and UVP features, but they require external resistors and capacitors to set the threshold voltages. Consult the datasheet and application note AN4391 for more information on implementing OVP and UVP.
The output capacitor value and type depend on the output voltage and current. A general guideline is to use a low-ESR capacitor with a value between 10uF to 47uF, with a voltage rating of at least 1.5 times the output voltage. Consult the application note AN4391 for more detailed guidance on output capacitor selection.
