STLDC08 - Step-up controller

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.

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.
