Triple-Output LED Driver Works With Common-Anode LED Strings

Focus:

An LED driver circuit based on the LT3496 powers three strings of LEDs with a common-anode connection, while also protecting the LEDs against high inrush currents in the event an LED string temporarily experiences an open circuit.

What you’ll learn:

• How to drive multiple LED strings with a common-anode connection
• How to protect LED strings against inrush currents due to intermittent connections
