Part Number: LM25066A

For first bring up, I must implement SMB bus for operation or it's enough to connect UVLO/OVLO and the peripheral components according to EVL that the gate FET will open and I will have 12V?

Hi Zalma,

You can connect UVLO/OVLO as per EVAL to get started with out needing SMBus

Best regards,

Hi Rakesh

Thanks for you help

I tried to operate the LM25066A but the FET is not open (Gate is 0), UVLO =1.5V and OVLO = 0.97V

Please help to check what I missed?

Hi Zalma,

Please remove D53 and connect the DIODE pin to GND. After doing this change please share the start-up waveforms with following signals.

VIN, VOUT, GATE, ENABLE, and TIMER
