A good PCB layout for the MAX5035BASA+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 MAX5035BASA+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 MAX5035BASA+T is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure proper thermal management and consider derating the output current at high temperatures.
Use an oscilloscope to monitor the output voltage, input voltage, and COMP pin voltage. Check for proper component values, PCB layout, and input voltage range. Consult the datasheet and application notes for troubleshooting guidelines.
