The input voltage range must be 0.5V greater than the output voltage. Use adequate ground plane and copper thickness adjacent to the converter.
All specifications are at nominal line voltage, Vout=nominal (3.3V for W5 models) and full load, +25 deg.C. Ripple and Noise (R/N) is shown at Vout=1V. See specs for details.
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.
