Atmel MSL1060 / MSL1061 LED Drivers

Atmel MSL1060 / MSL1061 LED Drivers

MSL106x are 6-string LED Drivers each incorporating a current mode boost regulator with a 50V internal switch and requires only a small inductor, output capacitor, and rectifier. The MSL1061 and MSL1064 also offer an I2C compatible serial interface. The wide 4.5V to 36V input voltage range makes these drivers suitable for many applications. 1MHz switching frequency allows small components while maintaining high efficiency. Each LED string powers up to 12 series LEDs, allowing a maximum of 72 LEDs. These ICs regulate LED current up to 25mA per string. They use a digital control loop that eliminates the need for external compensation components.

The MSL106x provide a 500:1 dimming range. Dimming is achieved via an external PWM signal with frequency up to 10kHz or by controlling the LED current using the IADJ pin (MSL1060) or the I2C serial interface (MSL1061/1064). String current can also be controlled with an ambient light sensor (ALS) and/or a negative temperature coefficient (NTC) thermistor based temperature sensor to modulate the string output intensity. This allows consistent light output over widely varying environmental conditions extending LED lifetimes.
