The SP6690 is a micro power boost regulator specifically designed for powering series configuration white LED. It features high output voltage, high efficiency, low quiescent current, and is suitable for single battery cell operation.
The SP6690 is a micro‑power boost regulator designed for series‑white‑LED applications, handheld computers and battery‑backup systems. It operates from a single cell (1 V‑4.2 V) and can boost the voltage up to 30 V while maintaining high efficiency and very low quiescent current.
The device is available in three compact packages (8‑Pin DFN, 5‑Pin TSOT, 5‑Pin SOT‑23) and includes built‑in protection for start‑up and short‑circuit conditions. Detailed electrical characteristics, performance graphs and ordering information are provided in the following sections.
