Samsung provides a reference PCB layout and thermal design guide in their application note AN-1228, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance, thermal management, and reliability.
The recommended power sequencing and startup procedure can be found in the datasheet, section 8.2. It's crucial to follow the specified sequence to prevent damage to the module and ensure proper operation.
Samsung recommends using low-ESR capacitors with a capacitance value of 10uF to 22uF for the input and output. The specific capacitor selection will depend on the application's requirements and operating conditions.
The SPMWH1228FD5WAPMSC has a built-in thermal monitoring feature. The temperature can be monitored through the TMON pin, which provides an analog output proportional to the module's temperature. This can be used to implement thermal protection and monitoring in the system design.
According to the datasheet, the maximum allowed input voltage deviation is ±10% of the nominal input voltage. Exceeding this limit may affect the module's performance, reliability, or even cause damage.
