Fully-integrated power device ideal for low-power mobile applications
(Product News, 02 Apr 2008 )
Enpirion has announced the availability of a new 600 mA synchronous buck converter with an integrated inductor, delivering extremely low output ripple in a tiny 3mm x 3mm x 1.1mm QFN package. The complete solution requires only 2 tiny MLCC capacitors for a solution footprint of only 22 sq mm. Enpirion's low noise devices are critical for today's RF, analog, and high-speed digital applications where switcher noise can limit data throughput and cause failure in spectral compliance.
As with all of Enpirion’s switch-mode converters, the new EP5368QI part features a proprietary low loss integrated inductor, PWM controller, MOSFETS and compensation network. This high level of integration greatly simplifies design, contains noise, and reduces part count and size. The device has a 4 MHz switching frequency, and achieves up to 94% efficiency. It provides 600 mA of continuous output current over the industrial temperature range, and 700 mA over the commercial temperature range.
