A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...
High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.
The PMP10596 reference design is an LED driver based on SIMPLE SWITCHER® LM46002 buck regulator. The driver board takes 24V +/-25% input voltage and supplies 700mA output current to drive up to 4 LEDs ...
This design example report discusses the 5 W universal input, CV/CC isolated flyback LED driver employing LYTSwitch™-2 LYT2002D. This design operates at an input voltage ranging from 90 VAC to 265 VAC ...
In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...
