Atmel LED Driver-MSLB9061

Atmel LED Driver-MSLB9061

LED 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 MSL1061, including fault detection,

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

generated PWM dimming.

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

prototyping, or 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.

DESCRIPTION

MSLB9061

Compact, 6-channel LED driver module

General Description

6-channel LED driver board is a

complete LED backlight driver

solution using the Atmel LED

Driver-MSL1061 LED driver

for medium-sized LCD panels.

Each channel drives up to 12

series-connected LEDs at up to

30mA per channel. The diver

board is configured to operate

from 3.3V up to 28V. The full-

scale LED current is preset to

15, 20, 25, or 30mA per LED

string, selected by an onboard

switch. Current can be

reduced from full-scale through

linear steps. Digital (PWM)

dimming is available through

an external signal or by using

the internal PWM generator via

the serial interface.
