Lower System Cost, High Design Flexibility

? Features eliminate or reduce cost of external components

? Fully integrated soft-start for minimum stress/overshoot

? Externally settable accurate current limit

? Wider duty cycle for more power, smaller input capacitor

? 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 ripple and limits DCMAX at high line

? Single resistor sets OV/UV thresholds, DCMAX reduction

? 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 for video applications

? Hysteretic thermal shutdown for automatic recovery

? Large thermal hysteresis prevents PC board overheating

? Standard packages with omitted pins for large creepage

? Active-on and active-off remote ON/OFF capability

? Synchronizable to a lower frequency

EcoSmart?– Energy Efficient

? Cycle skipping reduces no-load consumption

? Reduced consumption in remote off mode

? Half frequency option for high efficiency standby

? Allows shutdown/wake-up via LAN/input port
