Part Number: LM51770 Hello I have a question about the current supply capacity of the LM51770's gate driver. How many peak amps can it supply? By the way, the specs for the -Q1 model state that it has a peak current of 2A. Does this model have a higher…
Part Number: LM51770 Hi
I would like to know that about LM51770 ic control sequence. In specification chapter 9.3.1 Bi-Directional Power Backup . It seems it can be used in reverse mode to charge the input battery. But I can't really understand how…
Part Number: LM51770 Tool/software: On page 23 of the LM51770 data sheet the acronym PFM is used. It is only used this once in the whole data sheet. I suspect it should be PSM, a typo, since that sentence is talking about the PSM operation. If not what…
Part Number: LM51770 Other Parts Discussed in Thread: CSD18502KCS , Hello,
I'm designing a buck-booster converter with the output controlled by a PWM signal. Our application requires Vin: 12V to 30V, Vout: 28V which can be adjusted down to 15V thru…
Part Number: LM51770 Which tool is more accurate. I am getting wildly different answers with the same inputs: 18-36VDC in, 20VDC out at 2.5 amps.
The spreadsheet recemmends 8.1 uH inductor. WebBench designs in a 33 UH inductor. I don't know how to reconcile…
Part Number: LM51770 Other Parts Discussed in Thread: LM5177 , TLV431 How to set up constant voltage and constant current functions for the application of LM51770 in 48V battery charging?
Could you please take a look at what specific functions this…
Part Number: LM51770 Other Parts Discussed in Thread: LM5171 Tool/software: Hi,
I want to build a Li-Ion battery cycling (charging / discharging) system with an extra battery as an energy buffer, means the battery under test is discharged into the buffer…
Part Number: LM51770 I am designing a power supply with this part. I am having trouble with the Compensation Resistor calculations.
There are 2 diffeerent formulas in the datasheet, equation 3 and 46.
The value for A-CS is not in the datasheet…
Part Number: LM51770 Is it necessary to have pull down resistors from gate to source at the MOSFET's that are driven bei LM51770? Or to put it in another way: If there are no pull down resistors from gate to source at the MOSFET's, will the Vgs be low…
Part Number: LM51770 Tool/software: Hello,
When I reviewed the datasheet of the LM51770 controller, I could not find any information about how much current it supplies to the switches. When I look at the application examples, this controller is used…
