The combination of an external circuit and a low-voltage microcontroller occasionally requires a significantly higher power-supply voltage. You can use either an external boost converter to increase ...

A family of synchronous boost converters in 1.5- by 1.5-mm packages can power up to five series of white LED backlights in smart phones, PDAs, digital still cameras, and other handheld electronics.

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 ...

Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...
