LEDs Deliver Voltage Indication And Adjustable Regulation

In a fashion similar to using stacked Zeners for voltage regulation, this LED circuit cleverly combines voltage reference and voltage indication. Fig 1. This voltage regulator circuit (a) uses green ...

Diagnose LEDs by Monitoring the Switch-Mode Duty Cycle

A change in the forward voltage (VF) for a string of series-connected, high-brightness LEDs (HB LEDs) can indicate deterioration or complete failure of one or more of the LEDs. Accordingly, this ...
