| Semiconductor SQ6601PT Off-Line Quasi-Resonance Flyback Switching Regulator Description The SQ6601PT is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back Quasi-Resonant (including low frequency PRC)fly-back converter type SMPS (Switching Mode Power Supply) applications. this IC realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external components count and simplifying the circuit designs. the device is provided in a five pin overmolded TO-220 style package, affording dielectric isolation without compromising thermal characteristics. (Note). PRC is abbreviation of "Pulse Ratio Control" (On-width control with fixed OFF-time). Features * Quasi-Resonant Operation * Low-loss, Pulse-Ration-Control standby mode * Under-voltage lockout with Hysteresis * Adjustable switching speed for EMI control * Low start-up circuit current (100uA max) * Active low-pass filter for stabilizing the operation in case of light load * Avalanche Energy Guaranteed MOSFET with high VDSS * Built-in constant voltage drive circuit * Built-in step drive circuit * Built-in low frequency PRC mode (20kHz) * Pulse-by-pulse Overcurrent Protection (OCP) * Overvoltage Protection with latch mode (OVP) * Thermal Shutdown with latch mode (TSD) * Over-molded Five-Pin Package www..com Ordering Information Type NO.
