Hi
We have built up a PMP5141 unit and hopefully managed to get all the mods in correctly, but when we load the 24V output the volts drop to around 22V even if the load is only 2A. Looking at the switching frequency it has dropped to around 70Khz, which is slightly below the minimum setting given by the resistors. My question is, is there a problem with the minimum frequency on the reference design (i.e. a typo in the schematic) or is it because there is something wrong with our circuit limiting the power through-put?
Thanks
Steve
