تراشه سوئیچینگ TOP243YN اصلی

TOP243YN Extended Power, Design Flexible, EcoSmart, Integrated Off-line Switcher آی سی TOP243YN از سری آی سی های سوئیچینگ و از خانواده TOPSwitch-GX Family می باشد که برای مدارهای منابع تغذیه سوئیچینگ AC/DC با بهره وری و راندمان بالا و اتلاف انرژی پایین (نسبت به سایر آی سی های سوئیچینگ) طراحی شده است. ولتاژ درین ماسفت آی سی تا 700 ولت با پیک جریان 1.44A می باشد.

Product Highlights

• 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
