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…
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…
Hi Harry,
Regard that answer you provided during our E-mailing where you emphasized that LM5123-Q1 was designed with gate drivers optimized for dual FETs :
Harry Hofner said: The LM5123 has been designed for high power applications. Therefore, the gate…
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 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 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 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,
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…
Hello Harry,
Thank you for your feedback. I believe this design is nearing the first prototype with revision 5.
Harry Hofner said: There is one thing that should still be changed: The LO track in layer 2 is now placed directly underneath the border between…
