Philips IC SMPS "cold side controller" P/N 612771-1 ?????????????? Philips
My brothers PTV crashed and one of the SMPS
controller IC's appears to be bad. The hot side controller IC P/N 612664-2 I have identified as a Motorola MC34056 But I can't seem to find any info on the cold side controller P/N 612771-1 Anyone know what the Motorola equivalent for this part is? (or any other equivalent for that matter) Or, I'd even settle for a tip on where I might be able to acquire the original. Damn. I wanted to post the Model number of the set, but the durn paper I wrote it on seems to be hiding from me. I guess that's what I get for cleaning up and getting things organized around here )`: Thanks Dave Moore |

put finger to keyboard and composed: My brothers PTV crashed and one of the SMPS controller IC's appears to be bad. The hot side controller IC P/N 612664-2 I have identified as a Motorola MC34056 That should be MC34065. P/N 612664-2 crosses to an NTE1765, as does the MC34065: http://www.nteinc.com/specs/1700to1799/pdf/nte1765.pdf But I can't seem to find any info on the cold side controller P/N 612771-1 FWIW, this URL claims that the IC is made by Motorola, not Philips, and is equivalent to an SC78104P: http://www.tv-forums.com/forum/TV_Eq...12771-1_P7816/ IIRC, the "SC" prefix denotes a special order. In any case, if the IC is what I think it is, then it is probably mask ROMmed. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

No NTE cross and no datasheets found by Google But Thanks anyway Franc. Dave Moore : : IIRC, the "SC" prefix denotes a special order.
