Atmel LED Drivers-MSL1061/MSL1064
6-string PWM LED Driver with Digitally Compensated, 1.1MHz,
48V Boost Regulator, ±1.5% Current Balance, I 2 C Interface
The MSL1061/64 incorporates a current mode PWM boost regulator with
50V internal switch and a wide, 4.75V to 36V input voltage range. The
General Description
The Atmel ? LED Drivers-
MSL1061 and MSL1064 are
LED drivers with integrated
boost regulators capable of
driving six LED strings at
30mA up to 48V for lighting
applications to 8W, allowing
up to 72 LEDs per driver
backlighting applications.
1.1MHz switching frequency uses a small-sized inductor and output capacitors
while maintaining high efficiency and low ripple voltage and noise. The boost
regulator uses digital control and requires no external compensation.
An I 2 C/SMB compatible serial interface operates up to 1MHz, giving access
to internal 8-bit PWM dimming and 4-bit analog current adjustment for 12-
bit current control. Individual string enable and fault reporting are available.
The MSL1061 operates with one of four I 2 C slave addresses selected from a
single input pin (AD0), whereas the lower cost MSL1064 has one fixed I 2 C
slave address.
The MSL1061/64 is also easy to employ without using an I 2 C interface,
dimming with an external PWM signal.
Analog dimming of LED string current is available for use with an ambient
light sensor (ALS) and/or temperature management with a thermistor or IC
temperature sensor.
The MSL1064 comes in a 5 x 5mm, 24-pin TQFN package, and the MSL1061
in a 5 x5mm, 28-pin TQFN. Both packages are lead-free, halogen-free and
RoHS-compliant, and operate over a -40°C to 85°C temperature range.
Applications
Long Life, Efficient LED Backlighting for:
? Notebook PCs and Desktop PC Monitors
? Medical and Industrial Instrumentation
? Portable Media Players (PMPs)
? Automotive Audio-visual Displays
Traffic Lights
Signage
