SP6655ER-L Détails du produit

DESCRIPTION
The SP6655 is a 400mA synchronous buck regulator which is ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6655’s proprietary control loop, 20µA light load quiescent current, and 0.3Ωpower switches provide excellent efficiency across a wide range of output currents. As the input battery supply decreases towards the output voltage, the SP6655 seamlessly transitions into 100% duty ratio operation, further extending useful battery life. The SP6655 is protected against overload and short circuit conditions with a precise inductor peak current limit. Other features include programmable under voltage lockout and low battery detection, externally programmed output voltage down to 1.0V, logic level shutdown control, and 140°C over temperature shutdown.

FEATURES
■ 98% Efficiency Possible
■ Small 10-Pin DFN Package
■ Ultra-low 20µA Quiescent Current
■ 625mA Inductor Peak Current Limit
