The recommended layout and placement for the MAX8902AATA+ 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.
The selection of the output capacitor for the MAX8902AATA+ depends on the output voltage, output current, and desired ripple voltage. A general guideline is to choose a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the output voltage. Additionally, the capacitor's ESR (Equivalent Series Resistance) should be low enough to minimize voltage ripple.
The MAX8902AATA+ has an absolute maximum input voltage rating of 28V. However, the recommended operating input voltage range is 4.5V to 24V. Exceeding the absolute maximum input voltage can damage the device.
The MAX8902AATA+ has a built-in overvoltage protection (OVP) feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values for the voltage divider. The device will shut down if the input voltage exceeds the set OVP threshold.
The thermal shutdown temperature of the MAX8902AATA+ is typically around 150°C. If the device's junction temperature exceeds this threshold, it will shut down to prevent damage. The device will automatically restart once the junction temperature drops below 130°C.
