widest VIN range (3.0 to 24 V). Its low-profile MLP package (which is available in a lead-free design) replaces one buck controller, two drivers, two FETs, and one boot diode, requiring 50% less space than comparable design solutions using discrete components (see Fig. 1). TinyBuck is intended for a wide range of applications, from entertainment electronics to portable medical equipment to notebook computers and blade servers. Texas Instruments’ products include TPS40131, which is a two-phase synchronous buck controller with integrated MOSFET drivers. It supports a 5-V output from a 1 to 40-V supply and is intended for use in graphics cards, networking equipment, servers, and other computer and telecommunications equipment. Intersil’s ISL8510 offers a standard buck controller, integrated boot diode and FETs for power regulation and frequency switching. It can handle a fixed voltage of 5 V or a variable voltage of 6 to 25 V. This general-purpose lead-free package is intended for applications 18 · prOjECT ANAlOg · Apr 08 such as handheld devices, wireless LAN cards and compact flash memory cards. ON Semiconductor manufactures packages such as its NUD3048 FET switch, which combines two MOSFETs for voltage regulation. It is intended for cell phones and other telecommunications applications. Vishay Intertechnology produces packages that integrate control MOSFETs, synchronous MOSFETs, and driver circuits. The company’s SiC714CD10 and SiC711CD10 can be used to design buck converters in point-of-load devices such as servers and routers. International Rectifier’s IRF4000 integrates four MOSFETs into a single package intended for use in power-over-Ethernet devices such as switches and hubs. The device can deliver up to 15 W per port, and it takes up only 20% of the space on a 48-port circuit board that discrete PoE MOSFETs would occupy. Fairchild Semiconductor also manufactures the lead-free Dual Power 56 (FDMS9620), which includes two specialized/optimized MOSFETs in a dual MLP 5 x 6 package. It incorporates an optimal synchronous buck power stage to improve energy efficiency and PCB space utilization. Its integrated, low-switching-loss “highside” MOSFET is complemented by a low conduction loss “Low Side” SyncFET for optimal efficiency. Furthermore, the location and positioning of the two integrated MOSFETs in this package are ideally laid out for design engineers. This package is best for regulating power in notebook computers as well as general point-of-load solutions. Whether engineers need to make their electronics smaller, faster, cooler, or more energy-efficient, integrated MOSFET solutions exist to help them make their products the best they can be. • Visit http://mosfets. electronicproducts.com to see full coverage of MOSFETs Sponsored by Fairchild Semiconductor www.fairchildsemi.com Visit http://mosfets.electronicproducts.com to see full coverage of MOSFET solutions.
