Synchronous Buck MOSFET Drivers Announced by Microchip Technology.MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged Drivers Provide Maximum Efficiency; Are Available in Small SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. and 3 mm x 3 mm DFN DFN Definition DFN Deutsches Forschungsnetz DFN Digital Freedom Network DFN Deafness DFN Day for Night (cinematography) DFN Discrete Fracture Network (geology/geophysics) Packages CHANDLER, Ariz. -- Microchip Technology  Microchip Technology (NASDAQ: MCHP) is a manufacturer of microcontroller, memory and analog semiconductors, founded in 1989 when Inc. (NASDAQ NASDAQin full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ), a leading provider of microcontroller and analog semiconductors, today announced the MCP (1) See Microsoft certification. (2) (MultiChip Package) A chip package that contains two or more chips. It is essentially a multichip module (MCM) that uses a laminated, printed-circuit-board-like substrate (MCM-L) rather than ceramic (MCM-C). 14628 (http://www.microchip.com/get/40078592349537) and MCP14700 (http://www.microchip.com/get/400785962615741) synchronous Buck MOSFET Drivers, which complement market trends toward "green" products by providing maximum efficiency in small packages. With both available in small 8-pin SOIC and 3 mm x 3 mm DFN packages, the new devices drive two N-Channel MOSFETs arranged in a non-isolated, synchronous Buck converter A buck converter is a step-down DC to DC converter. Its design is similar to the step-up boost converter, and like the boost converter it is a switched-mode power supply that uses two switches (a transistor and a diode) and an inductor and a capacitor. topology. They feature excellent latch-up immunity, enabling extremely robust applications in the consumer and computing markets, such as digital power conversion, DC-to-DC power supplies, three-phase BLDC BLDC Brushless Direct Current (motor) BLDC Boulder Labs Diversity Council motor control and telecom equipment. The MCP14628 MOSFET driver includes an enhanced light-load efficiency mode that conserves energy when the power supply is not in full use. The dual-input MCP14700 driver is ideally suited for controllers that utilize 3.0V TTL/CMOS logic, and can control the high and low sides independently, which optimizes the timing between the two sides and further maximizes efficiency. Additionally, the MCP14700 driver's timing can be adjusted to a wide range of external MOSFETs, giving designers more flexibility to use different types of MOSFETs in their applications. "Microchip has a full line of MOSFET drivers in popular packages, at competitive prices," said Bryan J. Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "The MCP14628 and MCP14700 MOSFET drivers provide robustness, latch-up immunity, and small packages, making them ideally suited for space-constrained switching applications requiring the utmost efficiency." Device Packaging, Pricing & Availability The MCP14628 and MCP14700 MOSFET drivers are available in 8-pin SOIC and 3 mm x 3 mm DFN packages, for $1.17 and $1.33 each respectively, in 10,000-unit quantities.
