PRODUCTION DATA
Due to the nature of the switching converter with a pulsating input current, a low-ESR input capacitor is required for best input-voltage filtering and for minimizing the interference with other circuits caused by high input-voltage spikes. For the PVINx pin, 2.5 μF of input capacitance (after derating) is required for most applications. A ceramic capacitor is recommended to achieve the low-ESR requirement. However, the voltage rating and DC-bias characteristic of ceramic capacitors must be considered. For better input-voltage filtering, the input capacitor can be increased without any limit.
Use the correct value for the ceramic capacitor capacitance after derating to achieve the recommended input capacitance.
The preferred capacitor for the converters is one Samsung CL05A106MP5NUNC: 10 μF, 0402, 10 V, ±20%, or similar capacitor.
