TS1916 Overview
The TS1916 is a step-up (Boost) converter designed for driving up to 10 series white LEDs for backlighting application. The TS1916 uses current mode, 1MHz fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. It’s low feedback voltage reduces power loss and improves efficiency.
