A good PCB layout for the FAN73895MX involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. It's also recommended to use a shielded inductor and to keep the switching node (SW) away from sensitive analog circuits.
When selecting an inductor for the FAN73895MX, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100 mΩ. Ferrite or iron powder cores are good options.
The FAN73895MX is rated for operation up to 125°C ambient temperature, but the maximum junction temperature (TJ) is 150°C. It's essential to ensure proper thermal design and heat sinking to keep the junction temperature within the specified range.
Yes, the FAN73895MX can be used in a synchronous rectification configuration. In this case, the internal switch is used as the main switch, and an external N-channel MOSFET is used as the synchronous rectifier. This configuration can improve efficiency, especially at higher output currents.
The output voltage of the FAN73895MX can be adjusted by using a resistive divider network between the output and the FB pin. The resistors should be chosen to provide a stable voltage reference, and the ratio of the resistors determines the output voltage. A good starting point is to use a 1% tolerance resistor for the upper resistor and a 0.1% tolerance resistor for the lower resistor.
