Integrated 8-Channel LED Drivers with
Switch-Mode Boost and SEPIC Controller
ELECTRICAL CHARACTERISTICS (PWM CONTROLLER) (continued)
(V_CC = +15V, V+ = +3V to +5.5V referenced to PGND, R_T = 10kΩ, C_T = 3.3nF, REF = open, COMP = open, C_REF = 0.1µF, V_FB = 2V,
CS = AGND, AGND = PGND = 0V; all voltages are measured with respect to AGND, unless otherwise noted. T_J = T_A = -40°C to
+125°C, unless otherwise noted. Typical values are at T_A = +25°C.) (Note 1)
