Part Number: LMR51420 Hello! I am trying to use the equations in section 9.2.2 in the LMR51420 datasheet to solve for inductor and capacitor selections. However, using the example design targets in table 9-3 does not give me the same values given throughout…
Part Number: LMR51420 I am trying to build a ±12V power supply for my PCB project. The datasheet says VFB is 0.6V. Is it ok to simply swap the GND and VOUT in the reference design to achieve negative 12V power supply?
Part Number: LMR51420 Other Parts Discussed in Thread: LMZM23600EVM , LMZM23600 I am using LMR51420YFDDCR (1.1MHZ, FPWM) in this configuration:
Vout:3.3V, L=3.3uH, Cout=88uF, Iout=50mA
And I am getting the following output voltage with low frequency…
Part Number: LMR51420 Im using LMR51420XDDCR to convert from 21V to 3.3V. I use 3.3uH inductor and 88uF output capacitance.
I wanted to reduce the switching ringing of output voltage.
To do that I add 50ohm resistor in series to bootstrap 100nF capacitor…
Part Number: LMR51420 Other Parts Discussed in Thread: LMZM23600EVM , LMZM23600 Hello,
I am using LMR51420XDDCR to step down voltage from 21V to 3.3V using 8.2uH inductor and 88uF MLCC at output.
I have light load of 60mA.
With that condition I…
Part Number: LMR51420 I am getting the following convergence error while trying to simulate a circuit using LMR51420, that I am unable to resolve
