ADVANCE INFORMATION
Input capacitors must be selected to provide reduction in input voltage ripple and high-frequency bypassing, which in return reduces switching stress on the power stage MOSFETs internal to the device. In this example, a 0.1µF, 25V, 0402 must be placed as close as possible to the PVIN pins of the device on the same layer as the IC on the PCB. In addition, 8 × 22µF ceramic capacitors are used and a 100µF bulk capacitor is used on the input.
