Hi Nithin,
Here is the efficiency of LMR36503 at light load conditions
NITHIN JAMES said: If the minimum load condition (10% of rated load) is not met, what would be the primary impacts on performance would be:
Usually the impacts could be…
Part Number: LM5165-Q1 We are preparing the FMEDA report for our own standard automotive module.
Unfortunately there is no related document inTI's website, unlike the other ICs.
Please share the document to me if you have.
BTW, I also need the…
Part Number: LM5165 Tool/software: I have a converter (Running in COT Mode) with Rt=38.3 kΩ, giving an operating frequency of 538 kHz as per TI WEBENCH simulation.
Circuit Parameters:
L=100uH
Rser.=1.3Ω
Cout=4.7uFx2
Vin 28Vdc
Vout 3.3 Vdc…
Part Number: LM5165 Tool/software: Hello,
Please can you confirm LM5165's behavior during output overvoltage fault i.e. when external overvoltage is applied on Vout pin.
My understanding is that as LM5165 prevents negative inductor current, the IC…
Part Number: TIDA-00666 Other Parts Discussed in Thread: LM5165
Hi buddy,
In TIDA-00666 designed for BLE transmitter with looped power, could you please help me understand how to provision the power to BLE with less than 3.6mA loop current? in the…
Part Number: LM5165 Tool/software: Hello,
I set Input current limit as 180mA typical through ILIM pin. Please help to answer below -
During startup condition, if the Input current reaches this limit. Will LM5165 be prevented from starting up ? or…
Part Number: LM5165 Hello, I am planning to use LM5165Y (Fixed 3V3 part) in my design for 0.1A load in COT mode. The input voltage to this part goes as low as 3.4V. Considering Equation 4 of section 7.3.4 of datasheet & considering Inductor's DCR of 0…
Part Number: LM5165 Hello, I am planning to use LM5165Y in COT mode. The load current is 20mA_minimum & 120mA_maximum. Please can you share is there a minimum load current requirement in COT mode for output regulation.
My understanding is that in light…
Part Number: LM5165 Tool/software: Hello,
In my application, Output setpoint is 3V3 but the Vin dips to 2.8V for 200us. Due to large bulk output cap, the Vout will be higher than Vin during that dip duration.
The enable pin is tied to Vin. My understanding…
Part Number: LM5165 Hello,
I'm having issues with a design including the LM5165 converter. The relevant portion of the schematic is shown below.
The converter is set to PFM mode. The converter is supplying a very low current (100uA) device. The input…
