Description: TOP250YN AC/DC Converters 210 W

A CLASS TOP250YN IC TOP250Y TOP250 AC/DC Converters Switcher IC Power Integrations 210W TO-220 3 Pin Leads Chip

Specification:

• 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
