Part Number: LMR51420 Tool/software: Hi team,
I'm working on reducing the high-frequency ripple in the output of an LMR51420XDDCR buck converter, which we've configured to output 5V.
We recently switched from the LMR50410Y5 to the LMR51420XDDCR because…
Part Number: LMR51420
Tool/software:
Hi,
I am using the LMR51420YDDCR as a buck converter. Here are my system specs:
Vin Range - 23 - 25 V
Vout = 5 V
Max Iout = 1.5 A
I am trying to determine the optimal current rating of the inductor needed…
Part Number: LMR51420 Tool/software: I'm trying to import the pspice model of LMR51420 into ltspice but I'm facing an error with spice device type.
It seems like the available pspice model is encrypted! Is it possible to provide unencrypted model…
Part Number: LMR51420 Other Parts Discussed in Thread: LMR51406 , LMR36501 Tool/software: HI team,
Customer uses LMR51420XF and found there are no phase margin. Customer think it's because the maximum output current is too small as 80mA.
Are there…
Part Number: LMR51420 Tool/software: We plan to use the LMR51420 in an industrial design, to provide 5V. The chosen variant will be YFDDCR, 1.1MHz, forced pwm. As we operate in a EMI critical environment we plan to add an input Pi Filter to suppress wire…
Part Number: LMR51420 Hi team, the converter shall be used in the following configuration: Vin: 5V, +-0.25V Vout: 3.3V Iout_max 2A f 500kHz For this configuration table 9-1 in the datasheet recommends an inductor of 8.2 µH.
The inductor shall be dimensioned…
Part Number: LMR51420 Hello,
We are planning to use the LMR51420 configured for 3v3 output in a new design to power a RS232 transceiver. The RS232 has a low power state (automatic power mode) where it consumes ~1uA. We are concerned this may be too…
Part Number: LMR51420 Other Parts Discussed in Thread: LMR33620 , I am using LMR51420YDDCR (1.1MHZ, PFM) in this configuration:
Vout:5.0V, L=6.8uH, Cout=20uF, Iout= from 0 to ~2A (tested with different load resistor)
If the load increases, I notice…
Part Number: LMR51420 I'm considering LMR51420Y. When I used WEBENCH, L1 was not readily available and parts that clearly exceeded the specs were output.
I would like to select this with another component, but considering the inductance of 4.7uH and…
Part Number: LMR51420 Hello,
I have developed a power supply converting 26VDC to 3.3V, 5.3V, 5.6V and 24V all on one PCB (about 1"x3"x0.062") with four LMR51420 switchers and total load is approximately 8W. My unit gets hot as it is very compact (72C…
