    I'm looking for a datasheet of the MR5060. Switching power supply controller. It's similar to the MR2920.

    First page of google showed the MR4000.pdf has data for the 4000 and 5000 series ICs including the MR5060;

    Thanks. I've seen that though. It is missing the information I'm looking for, the threshold of power supply voltage when it starts oscillation. I'd think it's 14V like the MR2920. But it's not, I measured it, it starts at 16 to 17V depending on temperature. That's too high for the voltage I get from the onboard PSU, but I don't know if it's normal or not.

    I just had another 2 minute google and it looks like there is no single datasheet for that MR5060.

    I think the best you will get is that MR4000/5000 series datasheet.
