The circuit in Figure 1 combines a V BE -referenced current source with a current mirror to implement a simple two-terminal, fully floating LED current sink or source. This approach is well-suited for applications in which tight current accuracy is ...

The low- to moderate-power system in Figure 1 provides the interface between a pulse-width modulator and a high-side IGBT (insulated-gate-bipolar-transistor) or MOSFET switch. You can use it to interface TTL or CMOS circuitry to an H-bridge if you ...

James Lockridge, Texas Instruments Electronic Design Rather than use a fixed-rail voltage source, it’s more efficient and flexible to utilize a current source so that performance remains consistent while supply rail and coil resistance ...

Diotec Semiconductor Standard LEDs are widely used for all kind of lighting purposes such as optical indicators and signal lights, marking lights, display backlights, interior and furniture lighting and much more. New approaches even use standard ...
