IRµoªíPOWIR+´¹¤ù²Õ°Ñ¦Ò³]­p(­^¤å¤º®e)

International Rectifier (IR) introduced two POWIR+ chipset reference designs, the IRPP3624-05A and IRPP3624-12A. Simplifying and accelerating circuit design, the reference designs target single-phase synchronous buck converter applications in computing and high-end consumer applications.



The POWIR+ chipsets, featuring IR's IR3624MPBF PWM control IC and companion HEXFET MOSFETs, are supported by these reference designs and IR's enhanced design services. The IRPP3624-05A is optimized for low-current applications up to 5A while the IRPP3624-12A targets at medium-current applications up to 12A. Both reference designs utilise the IR3624MPBF PWM Control IC, which features a switching frequency of 600 kHz at 3.3V at 5A and 1.8V at 12A to improve efficiency by up to 84%.



The IRPP3624-05A uses a dual SO-8 MOSFET, the IRF8910PBF, to reduce size and component count. The IRF7823PBF and IRF7832ZPBF SO-8 MOSFETs utilised 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.



The series of POWIR+ chipset reference designs is available immediately. Customised reference designs are available 1-2 weeks ARO, ordered through the POWIR+ chipset online design tool. IRPP3624-05A and IRPP3624-12A are RoHS compliant.
