Other Parts Discussed in Thread: LM5148-Q1 , SYNC-BUCK-FET-LOSS-CALC , LM5148 Hi all,
I have used the IC " LM5148-Q1 " for the design of the buck converter, where I have calculated all the values according to the IC datasheet also verified with the support…
Hello Jacob,
The rise and fall times on the LM5122 are specified with a load capacitance of 4700 pF. So dependent on the input capacitance of the circuit you have behind the HO, LO outputs, the rise and fall times will vary.
You can check in your circuit…
Hi Ryan,
the losses of the Buck low side MOSFET can be calculated with:
P_switch.loss = 2 * Deadtime * Fsw * Vsd * I_Out
Deadtime can be set to 50ns
Vsd = Forward Voltage of MOSFET Body diode
I may also use the Quickstart calculator which lets you set…
Part Number: LM5143DESIGN-CALC Other Parts Discussed in Thread: LM5143-Q1 Hi, Team,
Please let me confirm about "Effiency/Power Loss Analyzer shown in IM5143-Q1 Quickstart Design Tool. In the section of "Effiency/Power Loss Analyzer" in the file,…
Other Parts Discussed in Thread: TINA-TI Hi
I'm going to use Tina-TI to simulate the switching loss, conduction loss, and junction temperature of Mosfet.
but I can't find any Tutorial or Examples of Tina-Ti.
Can I simulate these with Tina-Ti? If…
Part Number: UCC2897A Hi Expert,
The engineer is adopted the UCC2897A into applicant.
Will need the power loss information to design the Primary mosfet and secondary mosfet.
But the webex tool is not friendly to select the desired Mosfet in.
So can you…
Part Number: LM5170 Hi,
where i can find power loss calculator that give the optimaze componnents and high efficiency?
can i simulate the LM5170 in the webbench?
Thank you.
Ilan Mazuz.
Hello Harish,
The 22A high, will need to estimate the losses. please use the design calculator spreadsheet and enter in the parameter for your requirements populating the MOSFET section. The MOSFETs will be the hottest devices. There in the calculator…
