Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

Buck-boost converters produce a regulated output voltage either less than or greater than the input voltage. When the input voltage is higher than the output, the converter acts as a buck. When the ...

The LTC3777 is a 150V high efficiency (up to 99%) 4-switch synchronous buck-boost DC/DC controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V ...

Many electronic systems require both positive and negative voltages to operate properly. Generating an efficient, low-voltage positive output from a higher voltage input typically entails the use of a ...

A buck-boost DC/DC converter is one of the most valuable tools in a power supply designer’s toolbox for dealing with a variety of power conversion scenarios. In these situations, input voltages can ...

Linear Technology Corporation has produced the LTC7812, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down ...

Analog Devices, which recently acquired Linear Technology, has unveiled the LTC3779, a high efficiency (up to 99%) 4-switch single inductor synchronous buck-boost DC/DC controller that is able to ...

The LTC7815 Power-By-Linear IC is a high frequency (up to 2.25MHz) triple output (buck, buck, boost), synchronous DC/DC controller that maintains all output voltages in regulation during automotive ...

Linear Technology Corporation has announced the LTC3871, a 100V/30V bidirectional two-phase synchronous buck or boost controller, suitable for 48V/12V automotive dual battery systems. Current 12V ...
