PRODUCTION DATA
A small filter capacitor may be placed on CS to GND, with short traces, to filter any ringing that may be present at light load conditions when driving MOSFETs with large gate capacitance. This capacitor may not be required in all designs; however, it is wise to put a place holder for it in your designs. The current sense resistor should be returned to the ground terminal of the input bulk capacitor to minimize the loop area containing the input capacitor, the transformer, the MOSFET, and the current sense resistor.
