SD1433 Frequently Asked Questions (FAQ)
-
STMicroelectronics provides a recommended PCB layout in the application note AN5096, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
-
The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the input voltage, and a capacitance value between 1uF to 10uF. Refer to the application note AN5096 for more detailed guidance.
-
The maximum output current capability of the SD1433 is 3A, but it's recommended to derate the output current based on the ambient temperature and PCB thermal design. Refer to the datasheet for thermal derating curves.
-
The SD1433 has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the GND pin. The value of the resistor determines the overcurrent threshold. Refer to the datasheet for more information on OCP configuration.
-
The EN (enable) pin is used to enable or disable the SD1433. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device during shutdown or low-power modes.
