XT1750 2MHz High-Brightness LED Drivers With High-Side Current Sense And 5000:1 Dimming ■ General Description The XT1750, step-down constant-current high-brightness LED (HB LED) drivers provide a cost-effective solution for automotive interior/exterior lighting, architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination applications. The XT1750 operate from a 4.5V to 28V input voltage range and feature a 5V/10mA on-board regulator. A high-side current-sense resistor adjusts the output current and a dedicated PWM input (DIM) enables a wide range of pulsed dimming. The XT1750 are well suited for applications requiring a wide input voltage range.
