Part Number: LM5123-Q1-DESIGNCALC Tool/software: Hi, in "LM5123 Boost Controller Design Tool" spreadsheet,
Ruvlo_bottom_calc doesn't seem to be catering for the 10uA hysteresis current.
e..g. with Vuvlo_on=21V, Vuvlo_off=18V, Ruvt 252k. It then shows…
Part Number: LM5123-Q1-DESIGNCALC Hi,
I ran into discrepancy between design calculator in Excel and Webench concerning values for COMP pin for LM5123 IC.
When I enter same input values in both cases, I get pretty much different values of resistor…
Part Number: LM5123-Q1-DESIGNCALC Hello!
I've encountered two differences between the design tool an the datasheet:
The datasheet mentions 470 p F for C_VREF (Section 8.3.7), the picture in the design tool states 470 n F.
Using an V_UVLO_ON of…
Hello Phil,
May I please ask you first, to properly fill in your personal information (The system only shows questionmarks instead of your name). Can you please provide me with the following information: Vin min and Iout max / maximum output power.…
Part Number: LM5123-Q1 Tool/software: Hi team, I am Mahmoud Alsheikh, Hardware Developer with paragon AG, Germany.
I try to design the lm5123-Q1 with following parameter:
Vin = 13V, Vout = tacking voltage from Audio single from 20V to 45V.
Power…
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: 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 Team,
My customer is evaluating the LM5123-Q1 under the following conditions and it works. - Vin: 8.5V to 21V (USB Type-C PD SPR: 9V to 20V range) - Vout: 45V (max) - Ioout: 1~2A
When the system enters Sleep…
Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM5122 , LM5125-Q1 , TPA3223 , LM5126-Q1 Tool/software:
Hi all,
i would have to questions about the Usage of the LM5123.
1. BIAS Supply: Is it possible to use a separate Buck Converter (V_IN…
Part Number: LM5123-Q1 Tool/software: Hi team,
My customer is using LM5123 and met SW point output undershoot issue.
They met the issue both in EVM and their own design board. Below is the figure from EVM testing.
Datasheet limits the voltage…
