Digital Cameras

MP3 Players

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.
