Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT3519IMS-2 are fixed frequency step-up DC/DC converters designed to drive LEDs, they have a built-in 45V, 750mA low voltage side switch and Schottky diode. The combination of traditional voltage feedback and unique rail-to-rail current sense feedback allows these converters to operate as constant voltage or constant current sources. The devices feature rail-to-rail LED current sense pins to provide maximum flexibility in selecting the converter configuration to drive the LEDs, which can be programmed externally via a sense resistor. An external PWM provides PWM dimming up to 3000:1 and a CTRL input provides analogue dimming.
