Part Number: LM5149-Q1 Other Parts Discussed in Thread: LM5149 , LM5148 I'm a engineer from ABB robot R&D
The application is 48V ->24V
the problem is when I apply 0.1A load to 24V, the output can't rise, can only rise to 0.3V.
but however…
Part Number: LM5149-Q1 For my application, I want to disable the Active EMI feature. Few questions:
1) I have a 41.2kohm pull down resistor on the CNFG pin to make my convertor primary, spread spectrum on, dual phase off. Will this pull down resistor…
Part Number: LM5149-Q1 Other Parts Discussed in Thread: LM5149 , TPS25750 , CSD19533Q5A Hi,
I have a question regarding my 16s BMS (Battery Management System) (design).
I intend to use a PD (Power Delivery) Type-C source exclusively for charging purposes…
Part Number: LM5149 Tool/software: Hello everyone,
I’m trying to simulate the LM5149 in PSpice for TI 2024. I’ve downloaded the LM5149-Q1 PSPICE Transient Model from the TI website and followed the provided steps.
After loading the file,…
Part Number: LM5149-Q1EVM-400 Other Parts Discussed in Thread: LM5149-Q1 Tool/software: Dear All,
we are finishing to design a buck from 48V to 30V up to 8A (single chip) and up to 13A (dual chips, dual phases) and we purchased two EVB...
Because, in…
Hi,
Please see my comments here:
1. The schematic has just one LM5149-Q1. I am assuming both the LM5149-Q1 designs are identical. My first suggestion would be to just test on one phase and check if you run into any issues. (This eliminates the fact if…
Part Number: LM5149-Q1EVM-400 Other Parts Discussed in Thread: LM5149-Q1 , LM5149 Tool/software: Hello,
I am trying to test LM5149 on the LM5149-Q1 EVM. Are the parts similar enough where if I replace the automotive IC with the catalog part, the EVM will…
Part Number: LM5190-Q1 Other Parts Discussed in Thread: LM5190 , LM5143 , LM5149 , LM5148 Tool/software:
hi Sir
I need to design an Constant current output circuit to driver Laser diode
1.Vin =24V ，48v is best
2.Vout = 5V/30A ，60A is best
did the LM5190…
Hello Noah,
It's not the VGSth its the Miller Plateau you need to consider to fully enhance the MOSFET.
Please refer to the LM5149 User guide and use same/similar FETs as seen therein.
