STMicroelectronics STLDC08
Step-Up Controller for LED Supply

STMicroelectronics' STLDC08 Step-Up Controller for LED Supply is optimized to operate from one or two NiCd/NiMH or alkaline cells. The STLDC08 Step-Up Controller is able to drive an external MOSFET (N-channel) enabling it for use with wide power levels. With hysteretic control on STMicroelectronics' STLDC08 Step-Up Controller, it eliminates the need for small signal control loop compensation. The STLDC08 Step-Up Controller for LED Supply integrates a FET driver for a precise PWM dimming. Typical applications include single/dual cell NiMH, NiCd, or alkaline batteries, small appliances LED lighting and portable lighting.

Features
  • Input voltage range from 0.8 V to 3.6 V
