Features eliminate or reduce cost of external ponents - Fully integrated soft-start for minimum stress/overshoot - Externally programmable accurate current limit - Wider duty cycle for more power, smaller input capacitor - Separate line sense and current limit pins on Y/R/F packages - Line under-voltage (UV) detection: no turn off glitches - Line overvoltage (OV) shutdown extends line surge limit - Line feed-forward with maximum duty cycle (DCMAX) reduction rejects line ripple and limits DCMAX at high line - Frequency jittering reduces EMI and EMI filtering costs - Regulates to zero load without dummy loading - 132 k Hz frequency reduces transformer/power supply size - Half frequency option in Y/R/F packages for video applications - Hysteretic thermal shutdown for automatic fault recovery - Large thermal hysteresis prevents PC board overheating Eco Smart - Energy Efficient - Extremely low consumption in remote off mode (80 m W at 110 VAC, 160 m W at 230 VAC) - Frequency lowered with load...
