Recommended circuit This series has been tested according to the following recommended testing circuit before leaving the factory. This series should be tested under load (see Figure 3). If you want to further decrease the input/output ripple, you can increase the capacitance accordingly or choose capacitors with low ESR (see table 3). However, the capacitance of the output filter capacitor must be appropriate. If the capacitance is too high, a startup problem might arise. For every channel of the output, to ensure safe and reliable operation, the maximum capacitance must be less than the maximum capacitive load (see Table 4).

Operation under minimum load will not damage the converter, however, they may not meet all specifications listed. 2. Maximum capacitive load is tested at input voltage range and full load. 3. All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. cui.com CUI Inc │ SERIES: PYB10 │ DESCRIPTION: DC-DC CONVERTER date 08/15/2013 │ page 6 of 6 REVISION HISTORY rev. description date 1.0 initial release 06/26/2013 1.01 updated spec 08/15/2013 The revision history provided is for informational purposes only and is believed to be accurate.
