Description
The STLDC08 LED driver step-up controller is
optimized to operate from one or two NiCd/NiMH
or alkaline cells. The IC is able to drive an
external MOSFET (N-channel) enabling it for use
with wide power levels. Hysteretic control
eliminates the need for small signal control loop
compensation. The IC integrates an FET driver for
a precise PWM dimming. STLDC08 comes in a
DFN10 (3 x 3 mm) package.
