  • LMZ12003: VIN short to Vout, or SS

    TI Thinks Resolved
    Part Number: LMZ12003 Tool/software: Hi sir I use the LMZ12003 to be the power board for FPGA it's short between Vin & Vout, when apply the 6 v to the VIn of LMZ12003 when no load, does it need a Dummy load in back of the LMZ12003? thanks

  • LMZ12003: LMZ12003 Enable Pin Control Mechanism

    TI Thinks Resolved
    Part Number: LMZ12003 Hello, I am attempting to use the LMZ12003 for a current limiting application. I would like to know if there is a way I can prevent potential damage to an IO bank to an FPGA that is driving the enable pin, since this enable pin is…

  • LMZ12003: How much output capacitance can I add to the design?

    TI Thinks Resolved
    Part Number: LMZ12003 Hello, I have a design with the LMZ12003 chip. I have added 5 capacitors in the VOUT pin with 100uF capacitance each. The reference design advises just one 100uF capacitor. Could the 5 capacitors be too much for the LMZ12003 ? I…
