GENERAL DESCRIPTION
The SP6650 is ideal for portable applications
that use a Li-Ion or 3 to 4 cell
alkaline/NiCd/NiMH input. The SP6650 extends
battery life with it’s unique control loop
scheme (patent pending), which maintains
high efficiency levels (> than 90%) over a
wide range of output currents. Features such
as Inductor peak current control, protects the
power supply from overload or short circuit
conditions, controls the startup current to
prevent output overshoot and excessive
battery drop, and gives the user more
flexibility in choosing an appropriate coil to
optimize solution cost, size and performance.
Other features include a dedicated pin for
manual shutdown, a battery low indicator, and
thermal protection.
The SP6650 is offered in a RoHS compliant,
lead free 10-pin MSOP package.
