Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hello,
I have used the Excel designcalc for the LM5123 but the minimum output capacitance displayed is 3454,50 uF which sounds like a lot. I have done the same calculations…
Part Number: LM5123-Q1 Tool/software: Dear Sir,
I want to use LM5123 as a boost module, I use webench to design the parameter, the input condition is same, eg. input 9V-15V，output 18V.10A， but the webench deliver another bom, how to set the input parameter…
Part Number: LM5123-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Good Morning We are testing a board where we used a LM5123-Q1 to boost UP an input voltage in the range of 9.5V - 16.0V to 11.9V. The input voltage will be, in normal operation…
Hi Harry,
Can you tell in this structure of LM5123-Q1 + NTMFS5C670NLT1G FET what will be the drive current ?
I asked it since I afraid that may influence on the heating dissipation of the FET because of long t-on/t-off as a result of adding resistor and…
Part Number: LM5123-Q1 Other Parts Discussed in Thread: BQ24650 Tool/software:
These images are from a LM5123-Q1 boost converter set to 16V target which then feeds a buck converter/battery charger. The left image is what happens if no resistor is…
Part Number: LM5123-Q1 Tool/software: Hi,
There is a Pspice file availabile on TI website. When I open the lib file, it is said : "* Model Usage Notes: 1. PSpice transient model is developed considering SIMPLIS model as reference."
As I more…
Part Number: LM5123-Q1 Hello. I have a design from TI Webench Power Designer using the LM51231. My input range is 9-22V and my output is 24V at 6A. However, that chip is out of stock. I would like to use the LM5123 as a drop in replacement, but the Webench…
Part Number: LM5123-Q1 Tool/software: Hello,
Regard the Bypass mode.
Does it work for all input voltages as defined in the datasheet for boost (3.8-42v) ? And does it also support 200W power transfer ?
For example, my application in its regular operation…
Part Number: LM5123-Q1 Other Parts Discussed in Thread: LM5121 Tool/software: Hi Harry,
Does the UVLO_EN pin allows when connected to a HOST (MCU) in addition to its resistor divider, to shut-down the LM5123-Q1 when pulled low by the HOST? Is it, as…
Part Number: LM5123-Q1 Tool/software: Hello,
I didn't understand from the datasheet how shall I choose the values for the Compensation filter of the error amplifier (Ccomp, Rcomp and Chf).
I did see the values in the EVM doc but I'm not sure what…
