DESCRIPTION
The SP6654 is a 800mA synchronous buck regulator which is ideal for portable applications that
use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6654’s proprietary control loop, 20µA light
load quiescent current, and 0.3Ω power switches provide excellent efficiency across a wide range
of output currents. As the input battery supply decreases towards the output voltage the SP6654
seamlessly transitions into 100% duty ratio operation further extending useful battery life. The
SP6654 is protected against overload and short circuit conditions with a precise inductor peak
current limit. Other features include programmable under voltage lockout, externally pro-
grammed output voltage down to 1.0V, logic level shutdown control, and an open drain power
good indicator when V
OUT
is above 94% of its programmed value.
