Tom gave me his PSP after frying it by using the wrong powersupply. The micro fuses were okay, so onto the SMPS! It’s self contained – up in the top left corner in the picture, but, on the other side of the board. I didn’t take a picture of that size for some reason. So, this supply is based on a Texas Instruments Power Management IC, TPS65250. Anyways, closest datasheet I could find online was for the TPS65050 series. I assume the rating are simply a bit different, or this is OEM’d. I’m thinking right now that the main switching transistor is shot…and since those SMD transistors are basically impossible to identify – since they never seem to have any text on ’em – I just pull random ones off of old broken computer motherboards and assume they’re close enough….they all have been so far.
