Overview
TOP232-234 ® TOPSwitch-FX Family ® Design Flexible, EcoSmart®, Integrated Off-line Switcher Product Highlights Lower System Cost, High Design Flexibility • Features eliminate or reduce cost of external components • Fully integrated soft-start for minimum stress/overshoot • Externally settable accurate current limit • Wider duty cycle for more power, smaller input capacitor • Line under-voltage (UV) detection: no turn off glitches www.
DataSheet4U.
com • Line overvoltage (OV) shutdown extends line surge limit • Line feed forward with maximum duty cycle (DCMAX) reduction rejects ripple and limits DCMAX at high line • Single resistor sets OV/UV thresholds, DCMAX reduction • 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 for video applications • Hysteretic thermal shutdown for automatic recovery • Large thermal hysteresis prevents PC board overheating • Standard packages with omitted pins for large creepage • Active-on and active-off remote ON/OFF capability • Synchronizable to a lower frequency AC IN + DC OUT - D M CONTROL TOPSwitch-FX S F C PI-2503-073099 Figure 1.
