Lower System Cost, High Design Flexibility

• 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.

EcoSmart – Energy Efficient
• Extremely low consumption in remote off mode (80 mW at 110 VAC, 160 mW at 230 VAC).
• Frequency lowered with load for high standby efficiency.
• Allows shutdown/wake-up via LAN/input port.
