The CXSU63168 is a step‐up DC/DC converter designed for driving up to 5 white LEDs in series from a single cell Lithium Ion battery with constant current. Because it directly regulates output current, the CXSU63168 is ideal for driving    light    emitting    diodes    (LEDs)    whose    light intensity is proportional to the current passing through them, not the voltage across their terminals. A single external resistor sets LED current between 2mA and 20mA, which can then be easily adjusted using either a DC voltage or a pulse width modulated (PWM) signal up    to    100KHz.    Its    low    104mV    feedback    voltage reduces power loss and improves efficiency. The OV pin    monitors    the    output voltage    and    turns    off    the converter if an over‐voltage condition is present due to an open circuit condition. The CXSU63168 is available in SOT23‐6 packages.
