STMicroelectronics offers a complete tool line, tailored to the LED Flashlight Evaluation Board Based on the L6920DA.

White LEDs are gaining popularity as sources of illumination due to their high efficiency and reliability. Typical forward voltage drop across a white LED is approximately 3.5 V. When these LEDs are powered from a single or two cell batteries, a boost converter is needed to boost the voltage to drive the LEDs. This evaluation board, based on the L6920DA, implements a high efficiency step-up converter which requires very few passive components to perform the conversion from the battery voltage to the selected output voltage or current. Startup is guaranteed at 1 V and the device operates down to 0.6 V. The device has a very low quiescent current of only 10 μA. An internal synchronous rectifier is implemented with a 120 mΩ P-channel MOSFET, replacing the conventional boost diode, to improve efficiency. This also could reduce the cost of the application since no external diode required.
