Maxim Integrated 

Integrated 8-Channel LED Driver with

Switch-Mode Boost and SEPIC Controller

ELECTRICAL CHARACTERISTICS (LED DRIVER)

(V+ = +3V to +5.5V, VAGND = VPGND = 0V; all voltages are measured with respect to PGND, unless otherwise noted. TA = TJ = -40°C

to +125°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
