Description
The LT3517 is a current mode DC/DC converter with an internal 1.5A, 45V switch specifically designed to drive LEDs. It operates as a LED driver in boost, buck mode and buck-boost mode, combining a traditional voltage loop and a unique current loop to operate as a constant-current source or constant-voltage source. It also features programmable switching frequency allowing optimization of the external components for efficiency or component size.
