  • Forum Post: stablizing battery charger without load

    David Knight
    I used LM25088 buck controller to create a lead acid battery charger. Since the product is a battery charger, I don't put much capacitance on output of buck converter, since battery is large capacitive load. The output capacitance is 6 pieces of 1206 1u x7r capacitors in parallel. The inductor is...

  • Forum Post: Ringing on Vin of LM2674 and RC snubber

    Eric Sarmiento
    I have inherent ringing on the input and output of the LM2674 switching regulator. The design flaw is in the traces being used to connect the regulator. However since our customer doesn't want us to respin the boards, we're being forced to look at other solutions. I came across using a RC snubber...

  • Forum Post: LM2674-5.0 protection diode from output to input necessary?

    Lars M��ller
    Hi, my pcb have 2 power connectors. One with an input voltage from 35VDC and the other with an input voltage from 5VDC. It's safe that only one of these are used at the same time. The 35VDC voltage used the switching regulator LM2674-5.0 to convert the voltage to 5VDC. My question is: Do i need...

  • Forum Post: lmz23605 output pin knocked to the ground

    Alexey Sheviakov
    To power the module with FPGA (TE0600-01 Trents Electronic) I use the chip lmz23605. No load (when the unit is not connected) at power chip is working properly. If I install the module and turn on the power, the chip lmz23605 fails (output pin knocked to the ground.) Tell me, what is the reason? Для...

    Colin R.
    Hello, First of all, thanks for taking the time to address my question/problem. I'm using the LMR62014XMF Demo Board in my test setup to step-up 5v to 12.6v. The 12.6v load is a heater filament, which draws about 165mA in my configuration. When the heater is first turned on, it can draw as much...
