About this manual

The document introduces the STEVAL-TLLOO3V1, an evaluation board designed for the STCF02 step-up/down current mode converter. This board facilitates the design of flash LED drivers by providing proper recommendations for PCB layout and external components.

The device supports five selectable operating modes via logic signals connected to three enable pins: Shutdown mode (with optional NTC temperature sensing), Torch mode, Flash mode, Middle flash mode, and a specific shutdown circuit to prevent LED burning during faults. The board drives a single flash LED with a forward voltage range of 2.7V to 5V.
