I'm having some problems with an a LT1301 step up DC/DC converter. I'm using the circuit that appears on the datasheet to convert 5V to 12V, but I'm getting periodic spikes on the output when loading with a LED. The spikes are high, +- 5 Volts around the 12 V signal.
I don't understand why it doesn't behave like the datasheet says, if this is the same circuit.
Thanks in advance.
EDIT1:I haven't enough reputation to post more than 2 links, but the spike duration is around 60 ns
