Siliconix Inc. (Santa Clara, CA), a subsidiary of Vishay Intertechnology Inc. (Malvern, PA), announced the new Si3867DV p-channel power MOSFET optimized for use in synchronous buck converters. The Si3867DV will be used for low-current, buck and inverter, dc/dc converters in end products, including cellular phones, SIP cards, PDAs, digital still and video cameras, and hard disk drives. Additional applications include notebook computer synchronous buck converters for auxiliary voltages and asynchronous buck converters for smart battery packs.
The new Si3867DV, packaged in the LITTLE FOOT® TSOP-6, features an on-resistance of 0.051 ohms, a low typical gate charge of 7 nC, on-resistance-times-gate-charge figure of merit of 0.36, and a low Qgd/Qgs ratio of 0.7. The Si3867DV is the first in a series of PWM-optimized, p-channel MOSFETs planned by Vishay Siliconix. Future entries in the series will include devices with -12V and -30V breakdown voltages and an optional on-board Schottky diode in a range of surface-mount LITTLE FOOT and PowerPAK® packages.
Samples and production quantities of the Si3867DV are available now, with lead times of 8 to 10 weeks for larger orders. Pricing for US delivery in 100,000-piece quantities is $0.29.
