hi,
I'm using 34063 to step down voltage from 24vdc to 5vdc.
I'm using the same components as mentioned in the datasheet.
I'm driving 3 relays using uln2803. the current consumption when all the 3 relays are operating is 70mA.
but as soon as my relays are operated the voltage starts falling.
when all the 3 relays are operated voltage falls to 2.1v.
this shouldn't happen since max current in datasheet is 500ma,.
please help.
Sid
