Power Control and 1MHz I 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
phase adjustment reduces unwanted LCD artifacts such as motion blur. Up

to 16 MSL3162s can share the same 1MHz I 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.
Atmel LED Driver-MSL3162
The MSL3162 adaptively controls the voltage powering the LED strings
is a compact, high-power,
using patented Atmel's Efficiency Optimizer control. The Efficiency Optimizer
16-parallel-string LED driver.
minimizes LED driver power losses while maintaining high current accuracy.
It uses internal current control
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
MOSFETs to sink up to
individual string PWM setting, the 6-bit global intensity, and the 8-bit thermal
100mA per LED string with
derating. One external resistor provides the global reference current for all the
better than 3% accuracy and
LED strings.

device I 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 -40C to +85C temperature range.
