Product Details
| 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. FEATURES ■ Up to 3000:1 True Color PWM™ Dimming ■ Wide Input Voltage Range Operation from 3V to 30V Transient Protection to 40V ■ Rail-to-Rail LED Current Sense from 0V to 45V ■ 45V, 750mA Internal Switch ■ Internal Schottky Diode ■ Constant-Current and Constant-Voltage Regulation ■ Boost, SEPIC, Buck-Boost Mode or Buck Mode Topology ■ Open LED Protection and Open LED Status Pin ■ Programmable Undervoltage Lockout with Hysteresis ■ Fixed Frequency: 400kHz (LT3519), 1MHz (LT3519-1), 2.2MHz (LT3519-2) ■ Internal Compensation ■ CTRL Pin Provides Analog Dimming ■ Low Shutdown Current: <1μA ■ 16-Lead MSOP Package APPLICATIONS ■ Automotive ■ Industrial ■ Constant Current Source ■ Current Limited Constant Voltage Source |
