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.
