SLVS875C January 2009 – November 2014 TPS54332
PRODUCTION DATA.
To simplify design efforts using the TPS54332, the typical designs for common applications are listed in Table 1. For designs using ceramic output capacitors, proper derating of ceramic output capacitance is recommended when doing the stability analysis. This is because the actual ceramic capacitance drops considerably from the nominal value when the applied voltage increases. Advanced users may refer to the in the section for the detailed guidelines, or use the WEBENCH tool (http://www.ti.com/lsds/ti/analog/webench/overview.page).
