STMicroelectronics' STLDC08 LED driver step-up controller for LED supply

Image of STMicroelectronics' STLDC08 Controller STMicroelectronics' STLDC08 is an LED driver step-up PWM controller that is optimized to operate with an input voltage ranging from 0.8 V to 3.6 V. The device is able to drive an external N-channel FET which makes it useful for various LED power levels. The 100 mV voltage feedback minimizes the power losses and provides an accurate current control loop. A unique, true PWM dimming control is implemented with a MOSFET connected between the LED string and ground. The IC features low power consumption (3 mA typical) which makes it suitable for power sensitive applications. STLDC08 is available in DFN10 3 mm x 3 mm package.

Features
  • Input voltage range from 0.8 V to 3.6 V
  • 20 V overvoltage protection
  • Series or parallel LED configuration
  • Drives N-channel MOSFET or NPN bipolar transistor
  • No control loop compensation required
  • FET driver for very precise PWM dimming
  • RDS(ON) can be used to control the inductor current limit
Applications
  • Portable LED lighting
  • Safety LED lights
  • LED backlighting
  • LED flashlights
  • Solar LED lighting
  • Generic LED driving battery supplied
  • LED applications running off low input voltage (0.8 V)
