Santa Clara, Calif.—Renesas Electronics Corp. has developed two power semiconductor devices with compact packages for use in DC/DC converters, which provide power to the CPU, memory, and other circuit blocks in servers and notebook PCs and other products.
The RJK0222DNS and RJK0223DNS integrate a pair of power MOSFETs in a single package, enabling DC/DC converter designs that are more compact. With a package size of 3.2 mm × 4.8mm × 0.8mm (max.), the RJK0222DNS and RJK0223DNS make it possible to reduce the mounting area by about half compared with Renesas’ previous-generation power MOSFET products.
Key highlights:
- Packaging: Measures 3.2mm × 4.8mm × 0.8mm (max.)
- Efficiency: 95.2 percent
- Switching frequency: 300 kilohertz (kHz)
- Input voltage: 12 V; output voltage: 3.3V
Pricing: Starts at US$0.55 per unit.
Availability: Samples are currently available with mass production scheduled to begin in December 2010.

I had to satisfy my curiosity on this one -the drain currents on the MOSFETs are 14A and16A, dissipation in 8W range. Essentially the package is dumping all the heat on to the board, so the burden is on the board designer to provide adequate cooling design!
