STMicroelectronics provides a recommended PCB layout in the application note AN4965, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The output capacitor value depends on the output voltage, output current, and desired ripple voltage. A general guideline is to use a capacitor with a value between 10uF to 22uF, and an ESR (Equivalent Series Resistance) of less than 100mΩ. Consult the datasheet and application notes for more specific guidance.
Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the device.
The MP33AB01 has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. The application note AN4965 provides a detailed example of how to implement overcurrent protection.
The thermal derating curve is not explicitly provided in the datasheet, but it can be found in the STMicroelectronics' Power Management Guide, which provides a general thermal derating curve for the MP33AB01 and other similar devices.
