  • 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.

    Key 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
