CCM 5V@360mA LNK306 Auto restarting

Hi
Is this ok? I'm trying to use this configuration to power up 3 relays and an esp12e but It's auto restarting. According to datasheets it should consume a little more than ˜300mA. I'm using an ES1J as freewheeling diode.
Diodes are 5V and ESP12E 3.3V. I have a stage of 5.5V with LNK306 and a second stage with LM1117-3.3V to ESP. L1 is a 680uH according to Pi Expert.

Hi,
Could you please check if the restating still exist with nothing more than 15 ohms 2W resistor connected to the output?
Best Regards,
