GENERAL 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 0.3Ω power swi tches
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.
