Users can customise standard reference power designs online

International Rectifier has expanded its myPOWER online design services by introducing its POWIR+ chipset reference designs and enhanced online design services, to simplify and accelerate power management circuit design.
The first series of POWIR+ chipsets brings together the company's IR3637SPbF and IR3637ASPbF application-tuned PWM control ICs and their companion hexfet mosfets for single-phase synchronous buck applications in computing and high-end consumer applications. The IRPP3637-06 A/-12 A/-18 A reference designs, available in three power levels of 6, 12 and 18 A, accelerate the design process while eliminating unnecessary design iterations, says IR. In addition to these three designs, users may modify any of the standard designs online at http://powirplus.irf.com to create custom circuits.
"IR's POWIR+ reference designs use carefully selected power semiconductors, passive components and inductors targeted at specific power levels, and placed on an optimised PCB layout, to deliver predictable electrical and thermal performance. In contrast to typical evaluation boards, these reference designs mirror real-world circuits as closely as possible, providing meaningful results for complex issues such as board layout, thermal design, and the optimisation of device interaction," said Carl Smith, marketing manager for IR's computing and communications products.
Each of the POWIR+ reference designs is available with a full suite of online simulation tools. When customising a standard reference design, a user adjusts system-level inputs to effect trade-offs in key performance criteria such as electrical efficiency, power loss, junction temperature, size and bill-of-materials costs. Once complete, the circuit can be immediately simulated online and then ordered as a fully-tested and characterised design. The designs can be customised for an input voltage range of 3-13,2 V, an output voltage range of 0,8-5,0 V, and switching frequencies of 400 or 600 kHz.
