TOP245F Datasheet | Power Integrations

.. TOP242-250 TOPSwitch -GX Family Extended Power, Design Flexible, ® Eco Smart, Integrated Off-line Switcher Product Highlights Lower System Cost, High Design Flexibility - Extended power range for higher power applications - No heatsink required up to 30 W using P package - Features eliminate or reduce cost of external ponents - 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 k Hz 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 AC IN + DC OUT - ® CONTROL TOPSwitch-GX PI-2632-060200 Figure 1.
