TOP246Y Integrated Off-line Switcher TO220/7 (13514)
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
