Atmel LED Drivers-MSL3167/MSL3168
16-string, White LED Drivers with Adaptive Power Control,
Simple PWM Dimming Interface, and Fault Handling
Note: This MSL3167/8 Datasheet Brief explains direct drive PWM use of
the device, including control of a single, external string power supply. The
General Description
The Atmel ? LED Drivers-
MSL3167 and MSL3168
compact, high-power, 16
parallel string LED drivers
feature internal current control
MOSFETs that can sink up to
30mA per LED string with
better than 3% accuracy.
These devices drive up to 10
white LEDs per string, for up
to 160 LEDs per MSL3167/8.
A single PWM input controls
the PWM period and duty
cycle for all strings.
device is configured to operate this way automatically at power-up. The
MSL3187/8 offer extended features not explained in this Datasheet Brief
that include additional fault reporting and management, an I 2 C serial interface,
and programmable power-up state. For information about these and other
MSL3187/8 features, refer to the full MSL3187/8 Datasheet.
The MSL3167/8 includes automatic fault management of string open circuit,
short circuit and over-temperature conditions. Faults are alerted on the FLTB
pin, and fault status is optionally available through the I2C/SMBus-compatible
serial interface.
The MSL3167/8 adaptively controls the DC-DC converter that powers the
LED strings using Atmel Adaptive SourcePower ? technology. This Efficiency
Optimizer minimizes power use while maintaining LED current accuracy.
A single, external resistor provides the global reference current for all the LED
strings. The MSL3167 operates all 16 strings in phase, while the MSL3168
calculates and applies a 1/16th PWM period delay to successive strings to
evenly spread the string power supply load across time.
The MSL3167/8 are offered in a wave-solderable, 32-pin SOP package
(1.27mm pin pitch) and operate over a -40°C to +105°C temperature range.
Applications
Long Life, Efficient LED Backlighting for:
? Televisions and Desktop Monitors
? Medical and Industrial Instrumentation
? Automotive Audio-visual Displays
