  • LV14340: Unexpected Output behavior near UVLO threshold despite stable VIN

    TI Thinks Resolved
    Part Number: LV14340 Hello, I am using the LV14340 synchronous buck regulator in a 12 to 5 V output design and observing unexpected behavior when the input voltage is near the UVLO threshold. Configuration: UVLO thresholds: EN pin resistor…

  • LV14340: Output stuck at 0.5V instead of 5V

    TI Thinks Resolved
    Part Number: LV14340 Tool/software: Hi, This is the circuit of my 12V to 5V converter. D13 is SSB43L-E3/52T(Schottky 4.0 Amp 30 Volt). The voltage at one end of C32 is 5.6V and on the other end is 0.5V. I had a similar circuit which worked…

  • LV14340: Output getting unstable

    TI Thinks Resolved
    Part Number: LV14340 Tool/software: Hi, I am using this circuit to convert 12VDC to 5VDC. Due to some mistake with the footprint we were unable to mount the D13 diode (Part : SK54-3G) on the PCB directly, so for the prototype we soldered one end…

  • LV14340 input 24v, the original design output 5V, but sometimes the actual output 18V or 24v, may I ask what the reason is? The following is the circuit design schematic diagram, and the R9 design USES 10K.

  • LMR51430: VOUT short to VIN

    TI Thinks Resolved
    Part Number: LMR51430 Other Parts Discussed in Thread: LV14340 , LMR14030 Tool/software: Hi team, my customer wants to find a buck with Vin:24V, Vo:5V and the peak output current is 3A. The load is the encoder part whose maximum Vin is 5.5V which means…

  • LV14360: SW abnormal at 1A load current and output ripple is too high

    TI Thinks Resolved
    Part Number: LV14360 Other Parts Discussed in Thread: LV14340 Hi team, customer find the SW is abnormal when use LV14340. the load is 8ohm, current is 1A. but from the SW waveform, it seems device work at light load, which result the high output ripple…
