ME8615AD7G

General Description The

 ME8615 is a single-stage power factor corrected buck LED driver, built-in high voltage power MOSFET. A LED lighting board 

can be implemented with few external components. No input bulk capacitor is required. To implement good power factor and

 low THD, constant on-time control is utilized with an external capacitor connected to the COMP pin. Precise constant-current

 control regulates accurate output current versus changes in input voltage and output voltage. The operating frequency is

 proportionally adjusted by the output voltage to guarantee quasi resonant operation with higher efficiency. ME8615 provides 

open-LED, short-LED, and over temperature protection features. The current limit level is automatically reduced to minimize 

output current in a over temperature condition.
