Atmel LED Drivers-MSL3163 and MSL3164
16-string White & RGB LED Drivers with Adaptive Power
Control, E2PROM, and SPI/I2C/SMBus Serial Interface
The MSL3163/4 adaptively controls the DC-DC converters that power the
LED strings, using Atmel's Adaptive SourcePower technology. These Efficiency
General Description
The Atmel LED Drivers-
MSL3163 and MSL3164
compact, high-power LED
string drivers use internal
current control MOSFETs to
sink up to 100mA per string,
with current accuracy and
matching better than 3%. The
MSL3163/4 drive 16 parallel
strings of ten white LEDs
each, for a total of 160 white
LEDs per device. Sixteen
interconnected devices control
up to 2560 white LEDs.
Optimizers minimize power use while maintaining LED current accuracy.
The MSL3164 features a 20 MHz SPI serial interface, and the MSL3163 offers
a 1 MHz I 2 C serial interface. Both interfaces support video frame-by-frame
LED string intensity control for up to 16 interconnected devices to allow active
area dimming. The devices include an advanced PWM engine that easily
synchronizes to a video signal, and per-string phase adjustment to reduce
unwanted LCD artifacts such as motion blur. Additionally, an on-chip E2PROM
allows the power-up defaults to be customized through the serial interface.
A unique combination of peak current control and pulse width management
offer simple full screen brightness control, versatile area dimming and
a consistent white point. One external resistor provides the global peak
reference current for all LED strings, and global peak current fine-tuning is
available through an 8-bit register. Global string drive pulse width is adjusted
with an 8-bit global intensity register, and individual string pulse width is
modulated with 12-bit registers.
The MSL3163/4 feature fault monitoring of open circuit, short circuit, loss
of video sync and over temperature conditions, and provides a fault output
to notify the system controller. Detailed fault status and control are available
through the serial interface.
The MSL3163/4 are offered in a 6 x 6 x 0.75mm, 40-pin TQFN package and
operate over the -40°C to 85°C temperature range.
