STLDC08
Step-up controller for LED supply
Features
■ Input voltage range from 0.8 V to 3.6 V
■ Overvoltage protection
■ Drives N-channel MOSFET or NPN bipolar
transistor
■ No control loop compensation required
■ FET driver for very precise PWM dimming
Applications
■ Single/dual cell NiMH, NiCd, or alkaline
batteries
■ Small appliances LED lighting
■ Portable lighting
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.
