DESCRIPTION
The LDS8160 is a dual-output RGB or 6-channel
white LED driver with three temperature
compensation circuits for each bank of two LED
drivers. It supports both RGB LED and WLED
backlighting and keypad in portable applications.
Three 8-bit DACs set the current level for each LED
bank (A, B, & C) from 0 to 25mA in 0.125mA steps.
Each channel contains a linear LDO current driver in
a common cathode (i.e., current source) topology.
The LDO drivers have a typical dropout voltage of
25mV at maximum rated current. This provides a low
power and low EMI solution in Li-ion battery
applications without voltage boosting and associated
external capacitors and components.
Three 12-bit PWM generators with “smooth”
logarithmic control support Temperature vs. LED
Luminosity adjustments as well, as RGB color
correction and dimming. The PWM generators are
2
programmed 8-bit codes are converted to 12-bit
resolution logarithmic steps of ~ 0.17 dB per step.
The PWM frequency is ~280 Hz to minimize noise.
TM
includes a multiplexed 10-bit ADC and digital
processing circuits. The algorithm continually
measures the V-I characteristics of the LEDs and an
on-chip temperature diode to determine LED junction
temperatures to within 5oC accuracy.
Three user-programmable temperature correction
tables (LUTs) store PWM adjustment codes for every
5oC increment from -35oC to 120oC. These codes
drive the PWM engine to adjust for luminosity
variations and/or high temperature current de-rating.
The three correction LUTs support independent
correction for 3-color RGB applications.
The EN logic input functions as a chip enable. A logic
HIGH applied at EN allows the LDS8160 to respond
2
supports use in multi-target applications. The device
operates from 2.3V to 5.5V.
The LDS8160 is available in a 0.4mm pitch 12-ball
WCSP or a 3 x 3 x 0.8 mm 16-lead TQFN packages.
