A good PCB layout for the MAX5035AASA+T involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance.
To ensure stability, make sure to follow the recommended component values and PCB layout, and add a small capacitor (e.g., 10nF) between the COMP pin and GND to improve phase margin.
The MAX5035AASA+T can handle input voltages up to 28V, but it's recommended to keep the input voltage below 24V for optimal performance and reliability.
The MAX5035AASA+T is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliability and prevent overheating.
To troubleshoot issues, check the input voltage, output voltage, and current, and verify that the component values and PCB layout match the recommended design. Also, check for any signs of overheating, such as excessive temperature or current draw.
