Linear Technology / Power: LT3956 DC to DC Converter

This tutorial will provide an overview of the LT3956, an 80 V high-side current sense DC/DC converter designed to operate as a constant-current and constant-voltage regulator. It is ideal for driving high current LEDs, charging batteries and supercaps, or as a high voltage general purpose boost converter. The LT3956 uses an internal N-channel MOSFET and can drive up to eighteen 350 mA white LEDs from a nominal 12 V input, delivering in excess of 25 watts. It incorporates a high-side current sense, enabling use in boost, buck, buck-boost or SEPIC and flyback topologies. This module will also look at what the LT3956 is and what it does; then it will take an in-depth look at its features and benefits, including a comparison to alternative offline LED drivers. Finally details will be given for obtaining additional product information.
