A good PCB layout for the MAX7461EUK+ involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
To ensure stability, ensure that the output capacitor is within the recommended range (10uF to 100uF), the input capacitor is at least 1uF, and the feedback resistors are within the recommended range (1kΩ to 10kΩ). Also, avoid using long feedback traces and keep the feedback network close to the IC.
The MAX7461EUK+ can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
The MAX7461EUK+ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.
The output voltage of the MAX7461EUK+ can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.25V), R1 is the feedback resistor, and R2 is the divider resistor.
