LT35191 - Brand New Linear Technology IC Chips
-
DESCRIPTION
LED Driver with Integrated Schottky Diode The LT®3519/LT3519-1/LT3519-2 are fi xed frequency step-up DC/DC converters designed to drive LEDs. They feature an internal 45V, 750mA low side switch and Schottky diode. Combining a traditional voltage feedback and a unique rail-to-rail current sense feedback allows these converters to operate as a constant-voltage source or constant- current source. Internal compensation simplifies applications.
