MCP1630 with 0.33V current limit clamp?

[Faringdon]

Hi,
If i am using MCP1630 and want a 0.33V current limit (instead of the 0.9v), then may i just feed the COMP pin from the output of an opamp with 1V at non-inv and diode from COMP to opamp output, and negative feedback from COMP to opamp neg input? (as per attached)

Yep, that will work great. Off you go and get that into production before China beats you to it.

cheers.

Thanks, the MCP1630 datasheet gives typ and min source currents from the EA output, but not max...so i was wondering from that point of view...i mean, technically, as you know, we shouldnt pull down an opamp output unless its deffo current limited, or, a transconductance error amp.
