The recommended layout and placement for the MAX8792ETD+ can be found in the Maxim Integrated Products' application note AN5141, which provides guidelines for PCB layout, component placement, and thermal management to ensure optimal performance and reliability.
To optimize the output voltage accuracy of the MAX8792ETD+, ensure that the input voltage is within the recommended range, use a high-precision external resistor divider for voltage feedback, and minimize noise and ripple on the input and output lines. Additionally, consider using a voltage reference IC, such as the MAX6126, to improve output voltage accuracy.
The maximum output current capability of the MAX8792ETD+ is 2A, but it can be limited by the thermal performance of the PCB and the ambient temperature. Ensure that the device is properly heatsinked and the thermal design is optimized to prevent overheating and reduce the risk of thermal shutdown.
The MAX8792ETD+ has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. The resistor values can be calculated using the formula provided in the datasheet to set the desired overcurrent threshold. Additionally, consider using an external overcurrent protection IC, such as the MAX471, for more advanced overcurrent protection features.
The recommended input capacitor value for the MAX8792ETD+ is 10uF to 22uF, with a voltage rating of at least 2x the input voltage. A low-ESR ceramic capacitor, such as the X5R or X7R type, is recommended to minimize input voltage ripple and ensure stable operation.
