Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

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 ...

A single synchronous buck-boost DC/DC converter can deliver high power due to its synchronous switching topology, but eventually the switching and/or conduction losses at higher power can overwhelm a ...

Linear Technology announces the LTC3115-1, a synchronous buck-boost converter that delivers up to 2A of continuous output current from a wide range of power sources from single-cell Li-Ion to 24V/28V ...

A new synchronous buck boost converter has been unveiled by Linear Technology. The LTC3536 is designed to deliver up to 1A of output current from a Li-Ion/Polymer source or 300mA from dual cell ...

A synchronous buck-boost converter, designed to deliver up to 1.5A of output current, has been introduced by Linear Technology. The device's 2.5 to 15V input and output voltage range provides a ...

Linear Technology's LTC3531/-3.3/-3.0 is a synchronous buck-boost converter that delivers up to 200 mA of output current to a fixed regulated output with inputs above, below, or equal to the output ...

If you are looking to replace halogen bulbs with LEDs, combining a rectifier bridge and a current-controlled synchronous step-up/step-down converter creates a high power factor driver circuit, writes ...

Linear Tech has brought out two synchronous current mode buck boost converters that deliver up to 600mA of continuous output current from a wide variety of input sources, including single- or multiple ...

We have a love/hate relationship with LiIon batteries. They pack all this power in such a small and light package. But for running 3.3 V devices, they’re cumbersome. They need to be stepped down a ...
