Manufacturer: Description:equal to 1.6V with sustained operation as low as 1.1V. The maximum LED drive current is easily programmed using one external current sense resistor in series with the LEDs. In this configuration, LED current provides a feedback signal to the FB pin, maintaining constant current regardless of varying LED forward voltage (VF). Depending on the MOSFET selected, the LX1744 is capable of achieving an LED drive in excess of 1.0W. The LX1744 provides simple dynamic adjustment of the LED drive current (0% to 100% full range dimming) and the LCD Bias output voltage (up to 15% typ) through separate IC interfaces.Each interface has an internal RC filter allowing designers to make these adjustments via a direct PWM input signal or an analog reference signal.Further, any PWM amplitude is easily accommodated using a single external resistor. The LX1744 is available in the 14-Pin TSSOP, and the miniature 16-Pin MLP requiring minimal PCB area. |
