Best Way to Boost 5V USB to 6V for LA4525 Stereo Amplifier IC Power Supply

I am working on a USB Stereo Amplifier, but my IC requires 6V to work properly (I am using a LA4525). Optimally, I would just boost the power from my usb port from 5V to 6V, but I may need to do something more elaborate, like boosting 5V -> 9V then 9V -> 6V with a regulator. I also saw "(this)":http://usb.brando.com/usb-to-6v-voltage-booster_p00092c042d015.html, but it is a bit much for what I am doing. I am both a hobbyist and a newbie to all this, so any advice would be appreciated, and specific IC's and Regulators numbers would be even better.

dude use IC7806 FOR 6V DC AND IC 7809 FOR 9V DC

Hello Justin,

Since I'm not a power supply guru, I had to do a search and came across this "thread":http://www.electro-tech-online.com/electronic-projects-design-ideas-reviews/114072-4-7v-6v-dc-dc-boost-converter-circuit.html, see comment #4, on doing somewhat the same thing. The "link":http://www.scribd.com/doc/12593359/usb-to-6v-0 references a document by ON Semi that uses an "NCP3063":http://www.onsemi.com/PowerSolutions/product.do?id=NCP3063 (1.5 A, Buck Boost Inverting Switching Regulator) in a "USB to 6vdc 0.3A USB CHARGER" circuit. Hope this helps.

Regards,
Bob

Be very careful with usb supplies There is a limit to how much current you can draw from a USB line If you exceed this limit you could damage the motherboard make sure you check the specs first before connecting

See Attached for more info

Hope this helps you

Thanks for your reply, I will look in it now.

Thanks for your reply, I am pretty sure I will not exceed because it is a 0.22W IC...
