Integrated 8-Channel LED Drivers with
Switch-Mode Boost and SEPIC Controller
ELECTRICAL CHARACTERISTICS (LED DRIVER)
(V+ = +3V to +5.5V, AGND = PGND = 0V; all voltages are measured with respect to PGND, unless otherwise noted. T_A = T_J = -40°C
to +125°C, unless otherwise noted. Typical values are at T_A = +25°C.) (Note 1)
