SP6656, 400mA Synchronous Buck Regulator with Dynamically Adjustable Voltage Output
Copyright 2006 Sipex Corporation
SP6656
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, 20A light
load quiescent current, and 0.3 power 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,
dynamically adjustable output voltage, logic level shutdown control, and 140°C over temperature
shutdown.
