  • LM25145: Set PGOOD to low when Vin drops 2V

    TI Thinks Resolved
    Part Number: LM25145 Hi Team, My customer is using LM25145 and he wants to set PGOOD to low when Vin drops about 2V from 12V. The Vout is 5V, used to power PMIC. PGOOD pin is connected to "power-on" pin of PMIC, which controls power on/off sequencing…

  • LM25145: slow edges down to 100ns

    Resolved
    Part Number: LM25145 Can I slow the LM25145 edges down to 100ns by using a resistor in the gate? Will slowing the edges down to 100ns create shoot-thru? Will the adaptive dead-time work with the 100ns slow edge? Will the adaptive dead-time run into…

  • LM25145: LM25145 Behavior Issue, Need Debugging Help

    Resolved
    Part Number: LM25145 I recently built a board using the LM25145 IC according to the power designer for 20V in, 1.6V out @10-12A. I soldered everything down and tested it for shorts, wired it up to 12V for testing, and the first thing it does is put out…

  • LM25145: Does PGOOD work as OVP function?

    TI Thinks Resolved
    Part Number: LM25145 Hi Team My customer is asking if LM25145 have OVP function to protect devices behind output of LM25145 when output of LM25145 is going to high. It seems LM25145 have PGOOD function, which will disable PGOOD pin if FB is outside ±0…

  • LM25145: How to deal with EP-pin

    TI Thinks Resolved
    Part Number: LM25145 Hi team, Could you tell how to deal with EP-pin? The ways to deal with EP-pin in the datasheet are not inconsistent. For example, EP-pin is connected to GND in the figure 46, however EP-pin is floating in the figure 57. So not sure…
