LMR51420: No phase margin and suggest a different device in P2P

Part Number: LMR51420

Tool/software:

HI team,

Customer uses LMR51420XF and found there are no phase margin. Customer think it's because the maximum output current is too small as 80mA.

Are there any ways to improve phase margin, and could you suggest different device about <500mA in P2P with LMR51420?

Hi Hayashi,

The customer could try increasing the output capacitance, however a lower current device may be better.

While these are not P2P, here are a couple options

The LMR36501 is definitely the best suited device for 80mA if they are willing to consider a different pinout.

Best regards,

Ridge
