คุณลักษณะ

• Texas Instruments TPS92691EVM-001 SEPIC LED Driver Evaluation Board
• The Texas Instruments TPS92691EVM-001 SEPIC LED Driver Evaluation Board is a fully assembled and tested SEPIC LED driver designed to power a single string in series.
• Accurate closed-loop LED current regulation is achieved using low-offset rail-to-rail current sensing amplifiers.
• This amplifier is compatible with either high-side or low-side current sensing implementations.
• The DC LED current set point can be varied in a 15:1 ratio that specifies the high impedance analog adjustment (IADJ) input.
• Integrated gate driver circuitry and proprietary PWM dimming logic are integrated to enable external serial FET PWM dimming with superior 100:1 dimming ratio.
• Universal LED driver with the ability to drive 1~20 series strings connected to a white LED
• Wide input voltage range: 4.5 V to 40 V
• Supports automotive start-stop and 65Vmax load dump transients
• Compatible with high-side and low-side current sensing resistor positions
• Simple circuit interface for setting LED current reference and PWM load cycle
• Instantaneous current monitor output for LED fault detection and mitigation
