The recommended PCB layout for the MAX5723AUP+ is to keep the input and output traces as short as possible, and to use a solid ground plane to reduce noise and EMI. Additionally, it's recommended to place a 10uF capacitor between the VIN pin and GND, and a 1uF capacitor between the VOUT pin and GND.
To ensure the MAX5723AUP+ is stable and doesn't oscillate, make sure to follow the recommended PCB layout, use a sufficient output capacitor (at least 1uF), and ensure that the input voltage is within the recommended range. Additionally, it's recommended to add a small resistor (around 10ohm) in series with the output capacitor to dampen any potential oscillations.
The maximum input voltage that can be applied to the MAX5723AUP+ is 5.5V. Exceeding this voltage may damage the device.
The MAX5723AUP+ is rated for operation up to 125°C. However, it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Consult the datasheet for more information on temperature derating.
The output voltage of the MAX5723AUP+ is set by the resistive divider network connected to the FB pin. The output voltage can be calculated using the formula: VOUT = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
