TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TB9120AFTG,” a constant-current 2-phase stepping motor driver for automotive applications.

LEDs emit light when biased in the forward direction. For quality performance, a constant current driver is required to compensate for LED voltage drops and changes with temperature. This ensures ...

how to light an LED using proper current limiting resistors. But from there he moves on to the juicy bits. He builds a transistor-based constant current driver, then adds voltage regulation for ...

It also can maintain more than 1 A of constant current for large strings of LEDs ... According to National Semiconductor, it maximizes the light output for systems while maintaining Energy Star ...

LED Driver for Lighting Market. The global LED driver for lighting market is set for remarkable expansion, projected to ...

A current source provides electrical energy with a constant current. The implication is that if the resistance of the load changes the current source will vary the voltage to compensate.
