The LT3755 is a 60V, high side current sense DC/DC converter designed to drive high current LEDs. Its 4.5 to 40V input voltage range makes it ideal for a wide variety of applications, including automotive, industrial and architectural lighting. The device uses an external N-channel MOSFET and can drive up to 14 1A white LEDs from a nominal 12V input, delivering in excess of 50W. It incorporates a high-side current sense, enabling it to be used in boost, buck, buck-boost or SEPIC and flyback topologies.
