Lower System Cost, High Design Flexibility
Extended power range for higher power applications
No heatsink required up to 34 W using P package
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
