  • TPSM5D1806: RENB formula for EN

    Resolved
    Part Number: TPSM5D1806 In section 7.3.10. the formula for RENB yields unusual values for RENB. For instance, when Vin is 12V, the formula is RENB = 110 / (12V - 1.1V) = 10.1kohms. When working this into the 1.2V EN threshold & the 100kohm "top" resistor…

    TI Thinks Resolved
    Part Number: TPSM5D1806 Hi, Please may I ask some questions on the TPSM5D1806? Setting the output with more a more accurate feedback resistor ratio I notice that the TPSM5D1806 recommends setting a lower feedback resistor of 10 kΩ, and calculating an…

  • RE: TPSM5D1806: Reg: TPSM5D1806 part failure

    Hi Rasif, the AGND and PGND needs to be connected at a single point. In the EVM for example is connected to the bottom layer thru couple VIAS. The Bottom layer is PGND. see below Top Layer Bottom Layer
