3 Summary

Based on the analysis and assessment of the PDLC dual-buck application circuit, the following conclusion can be made. The Dual Buck application circuit is lower-BOM, due to the integration of drivers and MOSFETs than the typical PDLC application circuit. The 35nS minimum on-time of the LM656x5 allows for high frequency operation and a large conversion ratio required to obtain the maximum AC voltage swing for a given input voltage. The buck application circuit also has a higher power density and higher FIT rate due to reduce component count. If a lower output current is required, a smaller current device such as the LMR604X0 can be used for this type of application.
