Here is an app note from Maxim describing the various SMPS regulator topologies for battery powered systems: This tutorial presents an overview of regulator topologies for battery-powered equipment. The discussion covers linear regulators, charge pumps, buck and boost regulators, inverters, and flyback designs. The importance of peak current is explained, and schematics of each topology […]
Steve Taranovich has posted this review of the TS3300 switching regulator coupled with an LDO in same package: Touchstone, with its first analog power management product, has enhanced such a function with the capability to use supply voltages down to 0.6V while still being able to deliver a 75 mA output current. The device […]
McZ writes in with an impressive step-down regulator: The TPS56221 is a high-efficiency synchronous switcher with integrated FETs, which achieves a power density of greater than 200W/in3 with greater than 90 percent efficiency at high loads. The easy-to-use SWIFT step-down regulator supports 25-A point-of-load designs for telecommunications, networking and other applications.
