A good PCB layout for the MAX31790ATI+T involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The input capacitor should be a low-ESR ceramic capacitor with a value of at least 10uF, and the output capacitor should be a low-ESR ceramic capacitor with a value of at least 22uF. The capacitor values can be adjusted based on the specific application requirements and the desired level of ripple rejection.
The MAX31790ATI+T can handle input voltages up to 40V, but it's recommended to keep the input voltage below 36V to ensure reliable operation and to prevent damage to the device.
The output voltage of the MAX31790ATI+T can be adjusted by using a resistive divider network between the output pin and the ground pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
The MAX31790ATI+T can deliver up to 1.5A of output current, but the actual output current may be limited by the input voltage, the output voltage, and the thermal performance of the device.
