Initially available in 40V versions, the family will be extended in the coming months with devices offering ratings of 30-60V. The first device in the series has a typical RDS(ON) of only 0.7mΩ (max 0.85mΩ) and a typical output capacitance (COSS) of 1930pF. Rated for 40V, the TPHR8504PL is supplied in an ultra-miniature SOP-Advance package measuring just 5x6mm.
Target applications for the ninth generation U-MOS family include DC/DC converters, synchronous rectification and other power management circuitry where low-power operation, high-speed switching and minimum PCB real estate are needed.
U-MOS IX-H MOSFETs are suitable for high-side and low-side switching in DC/DC converters and secondary side synchronous rectification in AC/DC conversion circuitry. By improving the RDS(ON)*A value, U-MOS IX-H technology supports die size reductions of 65% for the same RDS(ON) – or RDS(ON) reductions of 65% for the same die size compared to the previous 40V UMOS VI-H generation. In addition, a better trade off between output charge (QOSS) and RDS(ON) leads to increased efficiency. As a result U-MOS IX-H MOSFETs can help designers to reduce both power consumption and equipment size.
Designers will be able to choose from a variety of surface mount packages and, in future, also an option that offers dual-side cooling.
