International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
MOSFETs improve 12V-input converter efficiency
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.
The new Powir+ chipsets,including IR's IR3624MPBF PWM control IC and companion HEXFET MOSFETs, are supported by these new reference designs and IR's enhanced design services.
These new reference designs provide an extremely useful and simple way of designing onboard embedded single-phase synchronous buck convertors rated between 5 and 12A.
The online design tool configures the reference designs to meet specific requirements for a variety of input and output voltages, assuring a reliable and dependable reference design.
The IRPP3624-05A, optimised for low-current applications up to 5A, achieves 88.5% efficiency with 12V input and 3.3V output.
The IRPP3624-12A, targeting medium-current applications up to 12A, achieves 84% efficiency with 12V input and 1.8V output at maximum load.
Both reference designs make use of the IR3624MPBF PWM control IC that includes features such as pre-bias start-up, programmable over-current protection, and 0.6V precision internal reference voltage.
The IRPP3624-05A uses a dual SO-8 MOSFET, the IRF8910PBF, to reduce size and component count.
The IRF7823PBF and IRF7832ZPBF SO-8 MOSFETs used in the IRPP3624-12A allow higher current due to improved thermal and electrical efficiency.
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.
