Additional Infomation About Product

SC4524D 18V 2A Step-Down Switching Regulator POWER MANAGEMENT Features Description Wide input range: 3V to 18V The SC4524D 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 18V. The Precision 1V Feedback Voltage switching frequency of the SC4524D is programmable Peak Current-Mode Control up to 2MHz, allowing the use of small inductors and Cycle-by-Cycle Current Limiting ceramic capacitors for miniaturization, and high input/ Hiccup Overload Protection with Frequency Foldback output conversion ratio. The SC4524D is suitable for Soft-Start and Enable next generation XDSL modems, high-definition TVs and Thermal Shutdown various point of load applications. Thermally Enhanced 8-pin SOIC Package Fully RoHS and WEEE compliant Peak current-mode PWM control employed in the SC4524D achieves fast transient response with simple loop compensation. Cycle-by-cycle current limiting and hiccup overload protection reduces power dissipation during Applications output overload. Soft-start function reduces input start- up current and prevents the output from overshooting XDSL and Cable Modems during power-up. Set Top Boxes Point of Load Applications The SC4524D is available in SOIC-8 EDP package.
