LM25148: COMP pin range of control voltages?

Part Number: LM25148


We wish to use the LM25148 as a synch buck. But we need also to have an output current clamp, which can clamp the output current by pulling down the comp pin..(eg an opamp error amp, to pull down the COMP pin via a diode)....the thing is, to do this, you first  need to know the COMP pin range of control voltages?.....but datasheet doesnt tell. Do you know  these values?

  • Hi,

    The LM25148 has a configurable current limiting feature which I think is better suited to this application. If you need to disable the buck completely, then you should drive the EN pin of the device to disable it when you need to. 

    Please see Section 8.3.3 and Section of the datasheet.

    Best regards,
