The SC667 and SC668 current sink drivers with on-chip digital lighting effects are presented as reducing the total parts count and extending battery life compared to boost converters or charge pumps.

The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

Semtech Corp. announced the industry's first smart current sink LED backlighting platform with on-chip digital lighting effects for high-end handheld displays. Semtech Corp. announced the industry's ...

The thyristor or silicon-controlled rectifier (SCR) provides a convenient latching mechanism for switching power to a load. However, once the thyristor is triggered into conduction, it supplies no ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...
