Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5164 Because of PCB constraints, inductor coil cannot be placed same side with LM5164 and FETs.
what is better design?
1. short distance between switch FET and inductor with parallelly connected…
Part Number: LM5146-Q1 Hello sir,
I would like to simulate LM5146-Q1 using TI PSpice tool, but I can't find LM5146-Q1 PSPICE model, could you help to provide it?
Dear David,
Thank for your response.
About my DC-DC converter. We had designed new PCB. After assembly all component, Everything is ok. The output voltage is around ~12V as expected and all component work normally without overheat after 3-4 hour running…
Part Number: LM5146-Q1 Hi Team,
Thank you for all the help and support.
Can you please clarify whether the FIT rate provided in the screenshot taken from TI official page is provided at 55 degree celsius or 125 degree celsius?
Regards,
Ajit
Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5146 , LM5143 Hi,
In LM5146, Web page, i could see the Output Current Max mentioned as 30A. How can Controller IC has Power stage Output current limitation ? Does it mean that i cannot use it for…
Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5146 Hi,
In LM5146,
When En < 0.4V, Controller is in shutdown mode.
When 0.4 < En <1.2V, Controller is in standby.
In both the above cases, what will be the impedance across LO and PGND…
Part Number: LM5146 Hi TI Teams,
One of our customer reported that the temperature of LM5146 and external MOSFET (Q19 and Q20) is to high, even under no-load conditions. The schematic is as below:
The PCBA is double-layered.
Under no load, it gets very…
Part Number: LM5146-Q1 Hi, I'm trying to design with the LM5146-Q1 an output of 0.85V and 20A from a input voltage range of 8V to 36V (it has to withstand spikes voltages of 100V too).
From Webench and from the excel file I've got very high power dissipation…
