lm2576 psu for gainclone

i have a question for all..would it be worth using an lm2576 as a power supply chip for the gainclone..the reason i ask is that i would like to have a microcoontroller on my preamp so i can use an IR remote...basically i want to be able to turn the power amp on and off...if this is a bad idea, would you guys have any other suggestions of how i can integrate this remote control feature
