STMicroelectronics provides a recommended PCB layout in the VIPER100SP13TR application note (AN4571). It's essential to follow the layout guidelines to minimize electromagnetic interference (EMI) and ensure proper operation.
The transformer selection depends on the input voltage, output voltage, and power rating. STMicroelectronics provides a transformer selection guide in the VIPER100SP13TR datasheet. Additionally, you can use online transformer selection tools or consult with a transformer manufacturer.
The VIPER100SP13TR can operate up to 150°C ambient temperature, but it's recommended to derate the power output above 85°C to ensure reliable operation. Consult the datasheet for thermal derating curves.
The VIPER100SP13TR has built-in OVP and UVP features. You can adjust the OVP threshold using the OVSET pin and the UVP threshold using the UVSET pin. Consult the datasheet for more information on how to set the thresholds.
STMicroelectronics recommends using a low-ESR ceramic capacitor (X7R or X5R) with a value between 1 μF and 10 μF, depending on the input voltage and frequency. Consult the datasheet for more information on input capacitor selection.
