TOP253GN-TL, IC: PMIC; AC/DC switcher,SMPS controller; 59.4?72.6kHz; SMD-8C

• 15W (adapter), 25W (openframe) at 230VAC and 9W (adapter), 15W (openframe) at 85-265VAC O/P power
• Multi-mode operation maximizes efficiency at all loads, EcoSmart™- energy efficient
• Extended creepage between DRAIN and all other pins improves field reliability
• Frequency jittering reduces EMI filter cost, allows both primary and secondary sensing
• Line undervoltage (UV) detection prevents turn-off glitches
• Line overvoltage (OV) shutdown extends line surge limit
• Accurate programmable current limit, optimized line feed-forward for line ripple rejection
• 132KHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size
• Half frequency option for video application, fully integrated soft-start for minimum start-up stress
• Output OVP is user programmable for latching/non-latching shutdown with fast AC reset
