A good PCB layout for the MAX1836EUT33#TG16 involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces to reduce EMI and noise.
To ensure stability, make sure to follow the recommended component values and PCB layout, and add a 10nF capacitor between the VCC and GND pins to filter out noise.
The MAX1836EUT33#TG16 can handle input voltages up to 23V, but it's recommended to keep the input voltage below 20V to ensure reliable operation.
The MAX1836EUT33#TG16 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
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 or physical damage.
