Modules vs discrete power circuit design - which offers the best design cycle time? Whitepaper measures, says modules.

In recent history the march of power design technology has been towards the use of web-based simulation to ease the design chores of putting together power conversion circuits with discrete components (discrete in the sense that power converter ICs are surrounded with passive components and then placed on a pc board.) There is another trend in power circuits, however, and that is towards modularized PSiPs (power systems in package) PSiPs integrate the power converter MOSFET switches, control, compensation, and the inductor all into one IC-like package. You don’t need to go through the simulation step to select external components because they’re already inside the package, selected, matched, assembled, tested out, and verified as to noise immunity and interference. Companies that make PSIPs are Enpirion, Intersil, Linear Technology, Rohm, TI, Torex, Vicor, and Vishay. Prop...
