? Extended power range for higher power applications
? No heatsink required up to 34 W using P/G packages
? Features eliminate or reduce cost of external components
? 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 kHz 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
