Atmel LED Driver-MSLB9082

General Description

8-channel LED driver board

is a complete LED backlight

driver solution using the Atmel

LED Driver-MSL3162 for

medium-sized LCD panels.

Each channel drives up to 10

series-connected LEDs at up

to 160mA per channel. The

driver board is configured to

operate from a 10 - 16V input

voltage. The full-scale LED

current is preset to 50, 60,

70, or 80mA per LED string,

selected by an onboard switch.

Current can be reduced from

interface in 64 linear steps.

Digital (PWM) dimming is

available through an external

signal or by using the internal

PWM generator via the

serial interface.

LED Backlight Driver Module

The optional microcontroller board and graphical user interface (GUI)

software allow control of the driver board through a personal computer. This

gives access to the internal features of the MSL3162, including fault detection,

digital control of LED current, individual LED string on/off control, and internally

generated PWM dimming.

The compact eight-channel LED driver board is intended for evaluation,

prototyping, or small production runs. Gerber files and Cadence OrCAD layout

files are available to allow the circuit to be integrated into a larger system for

large production runs.
