17. OUTPUT FILTERING
The converter has built-in capacitors at the output to control ripple and noise. If desired, additional output capacitance can be
introduced at the input to the powered equipment. Recommended starting point: one 10μF tantalum and one 1μF ceramic capacitor in
parallel at the output.
18. OUTPUT NOISE MEASUREMENT SCHEMATIC
For proper output ripple and noise measurement, connect a 10μF tantalum and a 1μF ceramic capacitor across the output. Set the
scope bandwidth to 20MHz. Probe directly off of one of the capacitors, using a small ground clip to minimize measurement error.
