STMicroelectronics provides a recommended PCB layout in the application note AN5323, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The STX790A-AP can be configured for different output voltage ranges by adjusting the resistive divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage range. Additionally, STMicroelectronics offers a voltage calculator tool to simplify the process.
Although the datasheet specifies a maximum input voltage of 18V, the STX790A-AP can handle transient input voltages up to 22V for a short duration (typically 100ms). However, it's essential to ensure that the input voltage remains within the recommended operating range for reliable operation.
To ensure the STX790A-AP meets the required EMC standards, follow the recommended PCB layout and component placement guidelines, use a suitable input filter, and implement proper shielding and grounding techniques. Additionally, STMicroelectronics provides EMC-related application notes and guidelines to help designers meet the necessary standards.
The thermal derating curve for the STX790A-AP is not explicitly provided in the datasheet. However, STMicroelectronics recommends following the thermal management guidelines in the application note AN5323, which includes information on thermal impedance, junction temperature, and power dissipation. This will help designers ensure the device operates within a safe temperature range.
