SP6656 Product details

DESCRIPTION
The SP6656 is a 400mA synchronous buck regulator that is ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6656’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 SP6656 seamlessly transitions into 100% duty ratio operation further extending useful battery life. The SP6656 is protected against overload and short circuit conditions with a precise inductor peak current limit. Other features include externally programmable output voltage down to 1.0V, logic controlled output voltage selection, logic level shutdown control, and 140°C over temperature shutdown.

FEATURES
■ 98% Efficiency Possible
■ Small 3X3 10-Pin DFN Package
■ Ultra-low 20µA Quiescent Current
■ 625mA Inductor Peak Current Limit
■ Guaranteed Minimum 400mA Output Current
■ 2.7V to 5.5V Input Voltage Range
■ Output Adjustable Down to 1.0V
■ 100% Duty Ratio Low Dropout Operation
■ 80µA Light Load Quiescent Current in Dropout
■ Output Voltage Logic Selection
■ Ideal for portable designs powered with Li Ion battery
