The CXLE8606 is a step-up DC/DC converter with a constant current to drive white LEDs or similar. The device can driveh1m嘉泰姆

 up to eight LEDs in series from a Li-Ion cell. The LED current is set by the external resistor (R_SET) and is directly regulated h1m嘉泰姆

by the feedback (FB) voltage (typ: 200mV) across the external resistor R_SET.h1m嘉泰姆

To ensure maximum safety during operation, the output has integrated overvoltage protection that prevents damage toh1m嘉泰姆

 the device in case of some fault conditions. The OVP voltage can be programmed by two external resistors.h1m嘉泰姆

The CXLE8606 is available in a tiny SOP8/PP package.h1m嘉泰姆
