A good PCB layout is crucial for the MAX8596ZETA+T. Ensure that the input and output capacitors are placed close to the IC, and the power traces are wide and short. Also, keep the analog and digital grounds separate and connect them at a single point to minimize noise.
Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating. For output capacitors, select ones with low ESR, high capacitance, and a voltage rating that meets or exceeds the output voltage. A good starting point is to use 10uF to 22uF ceramic capacitors for both input and output.
Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the IC.
The output voltage can be adjusted by connecting a resistor divider network between the output pin and the ground pin. The ratio of the resistors determines the output voltage. Refer to the datasheet for the specific formula and example calculations.
The minimum input voltage required for the MAX8596ZETA+T to operate is 2.7V. However, the output voltage regulation may not be accurate below 3.3V input voltage.
