Synchronous buck-boost converters with four power switches can deliver very high efficiency while providing both step-up and step-down DC/DC conversion. Combining the capabilities of two separate ...

The MAX16834 is a current-mode high-brightness LED (HB LED) driver for boost, boost-buck, SEPIC, and high-side buck topologies. In addition to driving an n-channel power MOSFET switch controlled by ...

The SC5010 eight-channel, phase-shifted white LED driver employs PWM phase-shift dimming control, allowing LED drivers to fit into the LCD panel for displays as thin as 4 mm. Features include a 4.5V ...

Find a downloadable version of this story in pdf format at the end of the story. EXPONENTIAL GROWTH of LED lighting has ushered in a vast selection of integrated circuit devices to provide controlled ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...
