Integrated Off-line Switcher

TOP242-250 TOPSwitch®-GX Family Extended Power, Design Flexible, EcoSmart,® Integrated Off-line Switcher 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 Description TOPSwitch-GX uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault prot.
