New Micrel Family of Integrated FET DC-to-DC Buck Converters Provides Highest Performance at Optimized Solution Costs for 12V Input Rails
(firmenpresse) - SAN JOSE, CA -- (Marketwire) -- 02/27/13 -- Micrel, Inc. (NASDAQ: MCRL), an industry leader in high-performance Linear and Power solutions, LAN and timing and communications solutions, today rolled out its latest-generation SuperSwitcher II™ family of integrated MOSFET buck regulators optimized for the 12V rails, with 6A/9A/12A output supply current. The new MIC2405x family is comprised of six common-footprint, DC-to-DC buck regulators that leverage Micrel's proprietary HyperSpeed Control™ and HyperLight Load® architectures. The devices provide flexible, cost-effective solutions for distributed power systems, communications networking and infrastructure, and industrial applications. The / (6A), / (9A), / (12A) are currently available in volume quantities, with 1,000 quantity pricing starting at $0.91, $1.04 and $1.22 respectively. Samples can be ordered at: .
"Power supply designers today experience growing challenges in identifying flexible cost-optimized solutions for their high-power-density, small-real-estate needs," noted Brian Hedayati, vice president of marketing for high-performance linear and power solutions at Micrel. "Micrel's SuperSwitcher family utilizes Micrel's proprietary architectures to enable light-load efficiency and high-V(IN) to low-V(OUT) conversions over a wide range of output currents, at an attractive solution cost. This results in exceptional value for systems that require minimum board space and maximum efficiency in order to reduce the power supply heat representing more than 25 percent of the cost of cooling these systems."
The family of devices (/////) operates with a single-input supply voltage range from 4.5V to 19V, and delivers output currents of 6A, 9A and 12A respectively, all in small footprint MLF-28, 5mmx 6mm packages. The common footprint shared by all devices in this family enables current scalability which in turn provides design flexibility for the power supply designer. This family of regulators has been tailored to be Any Capacitor™ stable, independent of the output capacitance Equivalent Series Resistance (ESR), thus solving the perpetual problem of stability that power designers face when dealing with distributed output capacitance. Moreover, these buck regulators provide more than 95 percent peak efficiency and operate at 600kHz switching frequency with +/-1 percent of output voltage accuracy (with output adjustable down to 0.8V).
The regulators offer a full suite of protection features to ensure protection of the IC during fault conditions. These include under-voltage lockout to ensure proper operation under power-sag conditions, thermal shutdown, internal soft start to reduce the inrush current, and foldback current-limit and "hiccup" mode short-circuit protection. The devices also feature a power good (PG) output to allow simple sequencing. The regulators are available in a thermally enhanced 28-Lead 5mm x 6mm MLF® package.
