Renesas Technology Europe announces dual-type power MOSFET

RJK0383DPA incorporates dual power MOSFETs of two different types, composing a synchronous rectification DC/DC converter in a WPAK high-thermal-radiation package measuring 5.1 × 6.1 mm and 0.8 mm thick (max.)



The RJK0383DPA achieves higher power supply efficiency by using state-of-the-art 10th-generation power MOSFETs. For example, power supply efficiency when converting 12 V input to 1.1 V output is 91.6% (at 600 kHz switching frequency), the best in the industry. Power supply output current that power MOSFETs handle increases double from earlier dual-type products from Renesas Technology.



Enables more compact power supply design and higher mounting density through reduction of chip mounting area to half that of earlier dual-package power MOSFET configurations

By achieving higher power supply efficiency, the RJK0383DPA reduces the chip mounting area to about half that of a dual-package power MOSFET configuration, enabling a more compact synchronous rectification DC/DC converter and higher mounting density. The RJK0383DPA will be particularly effective for applications requiring compactness, such as mobile devices.



The RJK0383DPA will be followed by two additional products having different output current ratings, the RJK0384DPA and RJK0389DPA. Sample shipments of these will also begin in October 2008 in Japan.
