TS19376 1A Step-down High Brightness LED Driver SOT-89-5L Pin Definition: 1. SW 2. GND 3. DIM 4. CSN 5. VIN General Description The TS19376 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage. The device operates from an input supply between 8V and 32V and provides an externally adjustable output current of up to 1A. Depending upon the supply voltage and external components, the TS19376 can provide more than 15 watts of output power. The TS19376 includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current, and a dedicated DIM input accepts a wide range of pulsed dimming. Applying a voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a low current standby state Features Application ● Wide input voltage range: 8V to 32V ● White LED Backlighting ● Up to 1A output current ● High Power LED Application ● 5000:1 Dimming ● LED Lighting Equipment ● Single pin on/off and brightness control using PWM ● Up to 1MHz switching frequency ● Typical 5% output current accuracy ● High-Side Current Sense ● Hysteretic Control: No Compensation ● Adjustable Constant LED Current Ordering Information Part No. Package Packing TS19376CY5 RMG SOT-89-5L 1Kpcs / 7” Reel Note: “G” denotes Halogen Free Product.
