The CXLE8114 is a step-up DC/DC converter with a constant current to drive white LEDs or similar.
The device can drive up to eight LEDs in seriesfrom a Li-Ion cell. The LED current is set by theexternal resistor (RSET) and is directly regulated by the feedback (FB) voltage (typ: 200 mV) across the external resistor RSET.To ensure maximum safety during operation, the
output has integrated overvoltage protection thatprevents damage to the device in case of some fault conditions. The OVP voltage can be programmed by two external resistors.
