Part Number: LMR51440 Hi,
The datasheet for LMR51440 mentions an absolute maximum input voltage rating of -0.3 to 38V. Could you please provide information on the maximum allowable peak voltage for transient events, including the duration or pulse width…
Part Number: LMR51440 Tool/software: Hi,
As a part of the Proof of Design I am performing on my custom HW, which utilizes LMR51440SDRRR to convert 24V to 5V,
I measured the switching node between the LMR51440 and its inductor. The rising edge has…
Part Number: LMR51440 Tool/software: Hi,
In the related thread it is written that LMR51440 spice model was in development.
I know that the LMR514 5 0 is included in WEBENCH, but not the LMR51440.
Will TI release a spice model in the nearby future…
Part Number: LMR51440-CALC Other Parts Discussed in Thread: LV3842 , TPS560430 , TINA-TI , LMR54410 hello
im trying to look for LV3842 library for TINA
if you have any information, could you share where can i find it
Part Number: LMR51440-CALC Other Parts Discussed in Thread: LMR43610 I intend to perform DCDC circuit analysis using the SIMPLIS tool.
I would like to request the sharing of the SIMPLIS library for the LMR43610 component.
Part Number: LMR51440-Q1 Hi Expert,
My customer uses LMR51440SQDRRRQ1 to convert 12Vin to 8Vout @461kHz. When in light-load (400mA), the SW waveform looks instable with duty cycle. But the schematic LMR51440SQDRRRQ1.pdf looks good to me. Is this normal…

Part Number: LMR51440 Tool/software: I have built a 3.3 V regulator with a nominal UVLO-threshold at 13.75 V, with 100 kOhm from EN to VIN and 10 kOhm from EN to GND. I ramp up the input voltage at 0.1 V increments. When I step from 13.4 to 13.5 V, the…
Part Number: LMR51440 Tool/software: I am using the two LM51440SDRRR IC. I have a 12-volt input and a +5Volt and +3.3Volt outputs. I have included a picture of the schematic.
We are seeing 1.6mA of current into the circuit when +5Volt is off.
The…
