DESCRIPTION
The SP1937 is a step-up DC/DC converter for white
LED driver with constant current. The device can driver
one to four LEDs in series from a single cell Lithium
Ion battery. Internal functions include current limiting;
thermal shutdown and soft-start to prevent damage
operate status. The SP1937 DC/DC converter operates
at 1.2MHz and low output capacitor as small as 0.22uF;
apply to Lithium-Ion powered systems. A low 95mV
(Typ) reference voltage minimizes power loss in the
current setting resistor for better efficiency.
