The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input ripple and improve output stability.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and keep the output capacitor value within the recommended range. Additionally, avoid using a output capacitor with a high ESR (Equivalent Series Resistance) value.
The MAX772CPA can handle a maximum input voltage of 18V. However, it's recommended to operate the device within the recommended input voltage range of 7V to 15V for optimal performance and reliability.
The MAX772CPA is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage according to the temperature derating curve provided in the datasheet.
The output voltage of the MAX772CPA is adjustable using an external resistor divider network. The output voltage can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
