functions also include the LED short pro tection, open protection, and internal over temperature protection. The COMP p in controls the duty by connected an RC compensation network to ground and for ming the closed loop feedback control. To protect the external power MOSFET fr om being damaged by supply over voltage , the G8211 OUT pin voltage is clamped to about 12V. The G8211 impr
