Power designs go online
Chipset reference designs and enhanced online design services aim to simplify and accelerate power management circuit design.
International Rectifier has expanded its myPower online design services with the introduction of the 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 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

1kV rad-hard power MOSFET saves satellite space
International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
The IRPP3637-06A, IRPP3637-12A and IRPP3637-18A reference designs, available in three power levels of 6, 12 and 18A, accelerate the design process while eliminating unnecessary design iterations.
In addition to the three reference designs available, users may modify any of the standard designs online 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.

Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
MOSFETs improve power density on both sides
New from International Rectifier are two TO-220-packaged HEXFET power MOSFETs that maximise power density and performance in primary- and secondary-side DC/DC convertor circuits.
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.
Each of these fully tested and characterised POWIR+ reference designs is available with a full suite of online simulation tools.
Simulation capabilities include small- and large-signal analysis, switching waveforms, and performance analysis for all components.
The IRPP3637-06A is optimised for low-current applications requiring reduced sise and component count, and is achieved by using IR's latest IRF8910PbF dual SO-8 MOSFET.
The IRPP3637-12A is optimised for medium-current applications, using IR's latest IRF7823PbF and IRF7832ZPbF independent SO-8 MOSFETs to improve both electrical and thermal efficiency.
The IRPP3637-18A is optimised for medium-to-high-current applications that require excellent thermal performance while maintaining an emphasis on cost-effectiveness, and is achieved by using IR's latest IRLR8713PbF and IRLR7843PbF D-Pak MOSFETs.
When customising a standard reference design, a user adjusts system-level inputs to effect tradeoffs 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 to operate within an input voltage range of 3.0 to 13.2V, an output voltage range of 0.8 to 5.0V, and switching frequencies of 400 or 600kHz.
