A good PCB layout for the MAX8901AETA+T involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the input and output capacitors are of high quality and have low ESR. It's also important to decouple the input voltage with a capacitor and to use a low-ESR output capacitor.
The MAX8901AETA+T can handle input voltages up to 28V, but it's recommended to operate it within the specified input voltage range of 4.5V to 24V for optimal performance and reliability.
The output voltage of the MAX8901AETA+T can be adjusted by using a resistive divider network between the output and the FB 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 MAX8901AETA+T can deliver up to 1A of output current, but it's recommended to operate it within the specified output current range of 0.1A to 0.5A for optimal performance and reliability.
