The recommended layout and placement for the MAX8729EEI+ can be found in the Maxim Integrated Products application note AN4341, which provides guidelines for PCB layout, component placement, and thermal management to ensure optimal performance and reliability.
The MAX8729EEI+ output voltage can be configured using the FB (feedback) pin and an external resistor divider network. The datasheet provides a formula to calculate the required resistor values for a specific output voltage. Additionally, Maxim Integrated Products provides a voltage regulator calculator tool to simplify the design process.
The MAX8729EEI+ has an absolute maximum input voltage rating of 24V. However, the recommended operating input voltage range is 4.5V to 18V. Operating the device above the recommended input voltage range may affect its performance, reliability, and lifespan.
To ensure stability and prevent oscillation, it is essential to follow the recommended layout and placement guidelines, use a suitable output capacitor with a low equivalent series resistance (ESR), and add a small ceramic capacitor (typically 10nF to 100nF) between the VIN and GND pins to filter out high-frequency noise.
The MAX8729EEI+ is capable of delivering up to 2A of output current. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal conditions. It is essential to ensure that the device is properly heatsinked and operated within its recommended operating conditions to achieve the maximum output current.
