Atmel LED Driver-MSL3162
16-string, RGB and White LED Drivers with Adaptive
Power Control and 1MHz I 2 C/SMBus Serial Interface
The advanced PWM engine is easily synchronized to the video signal and
refresh timing using a built-in DLL multiplier and sync dividers. Per-string
General Description
Atmel LED Driver-MSL3162
is a compact, high-power,
16-parallel-string LED driver.
It uses internal current control
MOSFETs to sink up to
100mA per LED string with
better than 3% accuracy and
with up to 10 series white
LEDs per string, or 160 LEDs
per MSL3162.
phase adjustment reduces unwanted LCD artifacts such as motion blur. Up
to 16 MSL3162s can share the same 1MHz I 2 C/SMBus-compatible serial
interface, which is fast enough for frame-by-frame LED string intensity control
of 16 MSL3162s, or 2560 white LEDs in total.
The MSL3162 adaptively controls the voltage powering the LED strings
using patented Atmel's Efficiency Optimizer control. The Efficiency Optimizer
minimizes LED driver power losses while maintaining high current accuracy.
The MSL3162 uses 6-bit analog (LED current) dimming as well as 10-bit
PWM dimming control. PWM dimming is derived from the product of the 8-bit
individual string PWM setting, the 6-bit global intensity, and the 8-bit thermal
derating. One external resistor provides the global reference current for all the
LED strings.
The MSL3162 features fault monitoring of open circuit, short circuit, and over-
temperature conditions, with fault status available through the dedicated FLTB
output as well as the I 2 C/SMBus serial interface. It supports both individual
device I 2 C read/write and broadcast write commands, allowing multiple
MSL3162s to be configured simultaneously.
The MSL3162 includes on-chip user EEPROM, allowing customization of the
internal register power-up defaults.
The MSL3162 is offered in a lead-free, halogen-free, RoHS-compliant
package with a -40°C to +85°C temperature range.
