Its high ripple current, high voltage rating and low ESR make it more suitable for converter applications. The low output voltage ripple and small peripheral circuit size can be obtained by using ceramic capacitor. The X5R or X7R models are selected as output and input capacitors, which have better temperature and voltage characteristics. When the VIN voltage is greater than 15V, if the input capacitor is ceramic capacitor, the high voltage spike generated at the VIN pin will exceed 40V, which may cause permanent damage to the chip. Therefore, we suggest that customers using electrolytic or tantalum capacitors with better power consumption in the application of VIN>15V, can effectively protect chips and improve system reliability. When the VIN voltage is very fast, the internal circuit of the chip is too late to respond and the output voltage is prone to exceed the rated output voltage, that is, the output voltage overshoot., the overshoot of the output voltage is especially serious in the following: 1. VIN rising fast. 2. The output capacitance is small. 3. The output load is small. When the system has the output voltage overshoot, the customers can increase the output capacitance to alleviate this situation.
