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 ...
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 is about a 15 W, universal input, tube LED driver using LYTSwitch-5 devices. It is designed in a single-stage buck-boost topology to drive an 80 V LED load at 188 mA output ...
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 ...
