Hello I am Pengju Kong I am now at APEC 2012 to demonstrate our Intersil product ISL9443 and ISL9444 synchronous buck controller with three outputs. This controller has unique features that do not need any external components for the compensation because it has internal compensation networks and they have a very strong driver to power 25 amp for each output.
You can see here is the ISL9443 evaluation board. It's very high power density evaluation board for three outputs. The ISL9444 evaluation board for three channels each channel can provide up to 25 amp at 5 volt output. The difference between these two IC is that the ISL9444 provides independent enable signal and independent power-good signal. The real application for these two ICs are satellite set-top boxes, IP gateways and the cable modems. For more information please visit intersil.com. Thank you.
