STMicroelectronics provides a recommended PCB layout in the application note AN4899, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
STMicroelectronics provides a component selection guide in the datasheet, which includes recommendations for resistors, capacitors, and inductors. Additionally, the application note AN4899 provides more detailed guidance on component selection and layout considerations.
Although the datasheet specifies a maximum voltage of 40V on the VIN pin, it's recommended to limit the voltage to 36V to ensure reliable operation and prevent damage to the device.
The VN750-B513TR has a built-in overcurrent protection feature, which can be enabled by connecting the OCP pin to a resistor and capacitor network. The application note AN4899 provides a detailed example of an overcurrent protection circuit.
The recommended startup sequence is to first apply a voltage to the VIN pin, followed by the EN pin. This ensures that the device is properly initialized and configured before enabling the output stage.
