How does the cost compare to a discrete solution?

How does the cost compare to a discrete solution?

    As I stated in the presentation, the lowest cost option for a switch-mode power supply is a discrete solution that usually consists of a controller, external MOSFETs, an inductor/magnetics, capacitors, diodes and resistors. A micromodule regulator is a complete power supply in an “IC like” form factor. Clearly it will cost more than its “discrete” equivalent. However, a micromodule device requires no design or debug and is guaranteed to work immediately. Furthermore, the solution footprint and thermal performance characteristics are usually superior to those of a Discrete alternative. Thus, there is always a cost delta – how much depends on what you consider is more important in your business: time-to-market, limited internal power supply design capability, space or thermal constraints and so on.
