Use adequate ground plane and copper thickness adjacent to the converter. The input voltage range must be 13.2 Volts max. for Vout >= 3.63 V. Ripple and Noise (R/N) is shown at Vout=1V. See specs for details. All specifications are at nominal line voltage, Vout=nominal (5V for D12 models) and full load, +25 deg.C. unless otherwise noted. Output capacitors are 1 F ceramic and 10 F electrolytic in parallel. Input cap is 22 F. See detailed specifications. I/O caps are necessary for our test equipment and may not be needed for your application.
