The recommended PCB layout for the MAX5920BESA+ involves placing the device near the power source, using a solid ground plane, and keeping the input and output traces short and wide to minimize noise and EMI. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
To ensure proper thermal management, the MAX5920BESA+ should be mounted on a PCB with a thermal pad connected to a solid ground plane. The device should also be placed in a well-ventilated area, and heat sinks or thermal interfaces can be used to further reduce thermal resistance.
The MAX5920BESA+ can handle input voltages up to 60V, but it is recommended to operate within the specified input voltage range of 4.5V to 40V to ensure reliable operation and to prevent damage to the device.
The MAX5920BESA+ output voltage can be configured by connecting the FB pin to a resistive divider network that sets the desired output voltage. The resistive divider network should be designed to provide a voltage at the FB pin that is within the specified feedback voltage range of 0.8V to 2.5V.
The MAX5920BESA+ can deliver up to 2A of output current, but the actual output current capability may be limited by the input voltage, output voltage, and thermal management. It is recommended to consult the datasheet and to perform thermal calculations to determine the maximum output current that can be safely delivered.
