High-Voltage HB LED Drivers with

Integrated High-Side Current Sense

ELECTRICAL CHARACTERISTICS (continued)

(VIN = 12V, RRT = 12.4kI, CIN = CVCC = 1µF, CLFRAMP/CREF = 0.1µF, NDRV = COMP = DIMOUT = PWMDIM = FLT = unconnected,

VOVP = VCS = VPGND = VSGND = 0V, VISENSE+ = VISENSE- = 45V, VICTRL = 1.40V, TA = TJ = -40NC to +125NC, unless otherwise

noted. Typical values are at TA = +25NC.) (Note 2)

Note 2: All devices are 100% tested at TA = +25NC. Limits over temperature are guaranteed by design.

Typical Operating Characteristics

(VIN = +12V, CVIN = CVCC = 1FF, CLFRAMP/CREF = 0.1FF, TA = +25NC, unless otherwise noted.)
