Additional Infomation About Product

SC4524C 28V 2A Step-Down Switching Regulator POWER MANAGEMENT Features Description Wide input range: 3V to 28V The SC4524C is a constant frequency peak current-mode 2A Output Current step-down switching regulator capable of producing 2A 200kHz to 2MHz Programmable Frequency output current from an input ranging from 3V to 28V. The Precision V Feedback Voltage switching frequency of the SC4524C can be programmed Peak Current-Mode Control up to 2MHz for component miniaturization or it can be Cycle-by-Cycle Current Limiting set at lower frequencies to accommodate high step-down Hiccup Overload Protection with Frequency Foldback ratios. The SC4524C is suitable for next generation XDSL Soft-Start and Enable modems, high-definition TVs and various point of load Thermal Shutdown applications. Thermally Enhanced 8-pin SOIC Package Fully RoHS and WEEE compliant Peak current-mode PWM control employed in the SC4524C achieves fast transient response with simple loop compensation. Cycle-by-cycle current limiting and hiccup Applications overload protection reduces power dissipation during output overload. Soft-start function reduces input start- XDSL and Cable Modems up current and prevents the output from overshooting Set Top Boxes during power-up. Point of Load Applications CPE Equipment The SC4524C is available in SOIC-8 EDP package.
