STLDC08 Datasheet (STMicroelectronics)

STLDC08, Step-up controller

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.
