New buck regulators feature high efficiency and a thermally enhanced package
September 29, 2011 // Paul Buckley
Alpha and Omega Semiconductor Limited (AOS) has released the AOZ1050 and AOZ1051 high efficiency, simple-to-use synchronous buck regulators. Both AOZ1050 and AOZ1051 are available in a thermally enhanced exposed pad SO-8 package, delivering output current of 2 A and 3 A, respectively.
The new devices are well suited for a variety of consumer electronics applications such as LCD TV, set-top-boxes, DVD players and recorders.
The low on-resistance of internal power MOSFETs in these devices allows higher efficiency and less heat generation. The full load efficiency of AOZ1051 is 7% higher and IC surface temperature is almost 40 °C lower than that of the leading competitor. Adjustable soft-start time provides system designers with flexibility for power-up sequencing. Cycle-by-cycle current limiting combined with unique hiccup short-circuit protection ensure reliable operation under any abnormal conditions.
AOZ1050 and AOZ1051 are immediately available in production quantities. The unit prices for 1,000 pieces are $0.66 and $0.72, respectively.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
