TS1916

TS1916 1.7A Boost WLED Driver SOT-26 Pin Definition: 1. Switch 2. Ground 3. Feedback 4. Enable 5. OVP 6. VCC General Description 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. The OVP pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The TS1916 includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage in the event of an output overload. Features ● 2.5V to 5.5V operating input voltage range ● Drives up to 10 series white LEDs ● 1MHz fixed switching frequency ● Wide range for PWM dimming (200Hz to 200kHz) ● Internal 1.7A switching current limit ● Over voltage protection (OVP) ● Internal soft-start function ● Current limit and thermal shutdown protection ● Under voltage lockout Application ● Digital Still Cameras ● Portable Electronics ● PDAs and Palm-Top Computers ● Local Boost Regulator Ordering Information Part No. Package Packing TS1916CX6 RFG SOT-26 3kpcs / 7” Reel Note: “G” denotes for Halogen- and Antimony-free as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds Absolute Maximum Ratings...
