The XZ1608C is a step-up DC/DC converter designed for driving up to 12 white LEDs in series from a single cell Lithium Ion
battery with constant current. Because it directly regulates output current, the 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 5mA and 20mA, which can then be easily adjusted using either a DC voltage or a pulse
width modulated (PWM) signal. 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
is available in SOT23-6 packages
