The design of a switching power supply has always been considered a kind of magic
and art, for all the engineers that design one for the first time.
Fortunately, today the market offers different tools that help the designers. National
Semiconductor was the first company to offer the “Simple Switcher” software, and an
on-line simulation tool that allows the design and simulation of a switching power
supply. New ultra-fast MOSFETs and synchronous high switching freq
