Current Circuit: MOSFET bridge rectifier with low forward drop
by “Crutschow“, forum member on Electro-Tech-Online.com The lowest input to output voltage drop you can get with a standard bridge rectifier is nearly a volt through the two conducting diodes for each half cycle, even with Schottky diodes in the bridge. That can generate a dissipation of about a watt per amp of output current in […]

When should I use an LDO versus a switching regulator?
Both switchers and LDOs have their place in power distribution, as each has special attributes. With few exceptions, every electronic circuit needs at least one well-regulated, accurate, stable dc power rail at 12, 5, 3.3 V, or even at 1 V, and many systems need five, ten or more such rails. This power must come […]
