16V LINEAR LED DRIVER WITH  ADJUSTABLE CURRENT

DESCRIPTION

UTC ULL12 is a 16V linear LED driver with adjustable current as
high as 300mA (limited by heat dissipation of the IC package).
UTC ULL12 is designed to provide a constant current source
determined by an external sense resistor connected between
Vsense and Cathode. Less than 2.5% current error is realized when
input voltage changes from 1.3V to 16V. This device is designed
with a <100ppm temperature coefficient, which leads to a perfect
constant current under a wide environment temperature range.
UTC ULL12 uses the power from the negative terminal of the
LED string, an extra power trace from the input power of LED
lighting module is not necessary. The number of external component
is very limited, only a resistor and a capacitor.
