Adding charge pump and LDO components to a boost converter circuit creates a cost-effective power supply for LCDs and other portable applications.

The step-up switching-converter circuit in Figure 1 presents a familiar problem: If you shut down boost converter IC 1 by pulling its input low, external inductor L 1 and forward-biased Schottky diode ...

Identifying all of the individual loss contributorsenables the development of higher-order models for designing efficient boost-converter circuits.

Although most experts consider these choices acceptable, the converters provide positive output voltages. A negative-output voltage converter, however, can provide an alternative that you should not ...

STMicroelectronics’ L4985A/B and L4986A/B power-factor correction (PFC) boost converters look to simplify design and enhance flexibility by integrating 800V startup circuitry and additional valuable ...

This is a great read for the frugal hacker, or anyone who’s interested in boost/buck converters. Speaking of boost/buck circuits, we’ve got some more links for you.

Diodes has introduced a boost converter that can supply constant voltage or constant current to drive backlights, with a dimming ratio of 100:1.

We would love to see a roll-your-own boost converter circuit that include a switch or dial that lets you select common PSU voltage levels.
