MILPITAS, CA – January 20, 2010 – Linear Technology Corporation announces the LTC3788/-1, a dual output, high power synchronous step-up switching DC/DC controller that replaces the boost diode with a high efficiency N-Channel MOSFET. This eliminates the heat sink normally required in medium to high power boost converters. The LTC3788/-1 can produce a 24V at 5A output with up to 97% efficiency, making it ideal for high power automotive audio amplifiers, industrial and medical applications where a step-up DC/DC converter must deliver high power with low heat dissipation in a small solution size.

The LTC3788/-1 operates from an input voltage ranging from 4.5V to 38V during start-up, maintains operation down to 2.5V after start-up and can regulate an output voltage as high as 60V. The powerful 1.5Ohm onboard N-channel MOSFET gate drivers are capable of slewing large MOSFET gates quickly, minimizing transition losses and allowing for up to a 10A per channel output current. In addition, the LTC3788/-1 draws only 125µA when one output is active and only 200µA when both outputs are enabled.

The constant frequency current mode architecture allows for paralleled outputs. The LTC3788 includes a clock output, phase modulation (for multiphase applications), two separate power good outputs and an adjustable current limit. The LTC3788/-1 has a phase-lockable frequency from 75kHz to 850kHz or a selectable fixed frequency from 50kHz to 900kHz. It has adjustable cycle-by-cycle current limit protection and uses either a sense resistor or monitors the voltage drop across the inductor (DCR) for current sensing. In applications where the input voltage may sometimes exceed the regulated output voltage, the LTC3788/-1 is able to keep the synchronous MOSFET on continuously so that the output voltage follows the input voltage with minimal power loss. Furthermore, the LTC3788/-1 has adjustable soft-start and maintains ±1% reference voltage accuracy over an operating temperature range of -40ºC to 125ºC.

The LTC3788-1 is available in an SSOP-28 package and the LTC3788 is housed in a 32-lead 5mm x 5mm QFN. The 1,000-piece price starts at $4.12 each. Both versions are available from stock. For more information, visit www.linear.com.

SAN JOSE, California – January 19, 2010 – Real Intent  Inc., the innovator in automating the intelligence of formal techniques for design verification, announced today that it is shipping Ascent™ Lint Version 1.2.

Ascent Lint is the next generation lint tool in the Ascent early functional verification family of products.  It performs syntax and semantic Lint checks for today’s complex SoC designs.  Ascent Lint 1.2 now offers rules from STARC Policy, Verilog and SystemVerilog Gotchas, Reuse Methodology Manual (RMM), Principles of Verifiable RTL Designs, and rules based on Real Intent industry expertise.  These rules cover the following areas:

• Legal but dubious modeling indicating probable errors

• Differences between simulation and synthesis semantics

• Naming and RTL coding conventions

• Subset restrictions to enforce modeling clarity and reduce complexity

• Opportunities to improve simulation performance

• Operations with hidden or expensive implementation costs

• Downstream tool flow issues

• Network and connectivity checks for clocks, resets, and tristate-driven signals

• Module partitioning rules

• Testability

Ascent Lint features an extremely fast engine, low noise report, and is easy to use for debugging. 

“Real Intent is very focused on providing the tool chain for finding the maximum number of bugs early and economically,” commented Pranav Ashar, CTO of Real Intent, “Recognizing the importance of lint as the first and key part of this tool chain, the linter in Real Intent’s Ascent product family is tightly integrated into the HDL front end. Richer HDLs and billion-gate designs have combined to create the need for next-generation linters that understand language semantics and common programming idioms and do more than just syntax checking, all the while still delivering the high speed expected of a linter. Ascent Lint 1.2 is unique in the industry in terms of delivering this combination of speed, comprehensiveness and configurability.”

Pricing and Availability

Ascent Lint 1.2 is available now. Current customers using Ascent IIV can take advantage of an upgrade package at a reduced price. For pricing information, please email info@realintent.com.
