TOPSwitch-GX Family
Extended Power, Design Flexible, EcoSmart , Integrated Off-line Switcher
Product Highlights
Lower System Cost, High Design Flexibility Extended power range to 250 W 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 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 packages for video applications Hysteretic thermal shutdown for automatic fault recovery Large thermal hysteresis prevents PC board overheating
