HI all,
So i want to design a 12V 4A power supply. I am using the National Semiconductor Volt. Reg. Handbook from 1980, but section 8.3 isnt completely clear to me regarding the selection of the Bridge Rectifier.
It states that the RMS Capacitor current can be 2-3 times the load current, so in my case 8-12Arms. But it then goes on to say the Bridge Recfier should be rated for at least the full output current.
Im not sure if they mean the Output load current (in my case 4A) or the Capacitor Load current of 8-12Arms.
I have some spare GBJ2510 from a repair which i would like to use, they seem to be rated at 25A with heatsink or 4A without. So im not sure if i need to specifiy a heatsink, and the datasheet for this device just shows two power curves, with or without heatsink so i presume a 25A rating is with an Infinite Heatsink surely?
