LP5520TL

The LP5520TL is an RGB backlight LED driver for small format color LCDs. It offers small and simple driver solution without need for optical feedback, and produces true white light over wide temperature range. The device is available in 25 pin microSMD™ package.

The features of LP5520TL can be summarized as:(1)Temperature compensated LED intensity and color; (2)Individual calibration coefficients for each color; (3)Color accuracy X and Y 0.003; (4)12 bit ADC for measurement of 2 sensors; (5)Adjustable current outputs for R, G and B LED; (6)0.2% typical LED output current matching; (7)PWM control inputs for each color; (8)SPI and I2C compatible interface; (9)Stand-alone mode with 1 wire control; (10)Sequential mode for one color at a time; (11)Magnetic high efficiency boost converter; (12)Programmable output voltage from 5V to 20V; (13)Adaptive output voltage control option; (14)< 2 A typical shutdown current; (15)MicroSMD-25 package, 2.77 * 2.59 * 0.6mm.

The absolute maximum ratings of LP5520TL are:(1)V (SW, FB, ROUT, GOUT, BOUT):-0.3V to 22V; (2)VDDA, VDDD, VDDIO, VLDO:-0.3V to 6.0V; (3)Voltage on Logic Pins:-0.3V to VDDIO 0.3Vwith 6.0V max; (4)Continuous Power Dissipation:Internally Limited; (5)Junction Temperature (TJ-MAX):125°C; (6)Storage Temperature Range:-65°C to 150°C.
