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 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 I2C/SMB compatible serial interface operates up to 1MHz, giving access to internal 8-bit PWM dimming and 4-bit analog current adjustment for 12bit current control. Individual string enable and fault reporting are available. The MSL1061 operates with one of four I2C slave addresses selected from a single input pin (AD0), whereas the lower cost MSL1064 has one fixed I2C slave address. The MSL1061/64 is also easy to employ without using an I2C interface, dimming wi...
