STMicroelectronics provides a recommended PCB layout in the application note AN5323, 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 minimum of 10uF ceramic capacitor with a voltage rating of at least 1.5 times the input voltage. However, it's recommended to consult the application note AN5323 and perform simulations to determine the optimal capacitor values for your specific design.
The PD55003STR-E is rated for operation up to 105°C ambient temperature, but it's recommended to derate the output current and voltage according to the thermal derating curve provided in the datasheet to ensure reliable operation.
The PD55003STR-E has built-in OVP and UVP, but it's recommended to add external circuitry to enhance protection. A simple OVP circuit can be implemented using a zener diode and a resistor, while UVP can be achieved using a voltage supervisor IC. Consult the application note AN5323 for more details.
The output capacitor value and type depend on the output voltage and current. A general guideline is to use a minimum of 22uF ceramic capacitor with a voltage rating of at least 1.5 times the output voltage. However, it's recommended to consult the application note AN5323 and perform simulations to determine the optimal capacitor values for your specific design.
