Part Number: LM5123-Q1 Tool/software: I am working with LM5123, I was using its design sheet which I downloaded from TI website itself. for 48V Vout its limiting current to 2A, the datasheet has not specified 100W power dissipation, but the design tool…
Part Number: LM5123-Q1 Tool/software: Hello TI Team,
We are designing a DC-DC Boost, for 4V input & 12V output with 200W output power using LM5123-Q1.
We are looking Peak current rating of LO & HO pins (MOSFET Gate driving pins).
We need to calculate…
Part Number: LM5123-Q1 Tool/software: Hi, I have started designing with the LM5123 and have created a draft schematic. I have some questions and need some validations. 1-) The datasheet suggests a 1uF capacitor to be connected to the BIAS pin, but the…
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…
