The maximum input voltage that can be applied to the NCP1075AAP100G is 18V, although the recommended maximum input voltage is 15V for optimal performance and reliability.
To ensure stability, it's essential to follow the layout guidelines provided in the datasheet, use a sufficient output capacitor (at least 10uF), and keep the input capacitor (if used) as close to the VIN pin as possible. Additionally, avoid using long traces and minimize the loop area of the output capacitor and the inductor.
The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR can lead to instability and oscillations.
While ceramic capacitors can be used as output capacitors, they are not recommended due to their high ESL (Equivalent Series Inductance) and low ESR, which can cause instability and oscillations. Instead, use a capacitor with a low ESL and a minimum ESR of 0.1 ohms, such as an electrolytic or tantalum capacitor.
The output voltage ripple can be calculated using the following formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
