Part Number: LMR14030 Hi,
Customer use LMR14030 in 24V applicaiton, and found that it very easy burn out, the pins impedance are short to ground.
we measured the Vin voltage waveform and not found it higher than 40V. here is customer schematic, please…
Part Number: LMR14030 Hello,
We are using LMR14030SDDAR in our design for generating 4.3V.
Could you please provide your feedback on the below two queries on LMR14030SDDAR related to the FMEA (Open point during the review with OEM).
What is…
Part Number: LMR14030 Dear Teams,
Please forgive my silly questions. My customer is asking why the inductor current will keep constant once we short the output. Then, if the output short to GND recover, the inductor current will go to zero?
Thanks…
Part Number: LMR14030-Q1
Hi, TI experts,
Input voltage 12V, output 3.3V/1A
There are two questions:
1. When the input voltage rises rapidly, the output voltage will overshoot to 5.8V,why?
2. How can the Power Good pin show the waveform…
Part Number: LMR14030-Q1 Hi,
1. TI recommendations outlined in par. 7.3.6 of the LMR14030-Q1 datasheet define how to calculate resistors of ENABLE divider to have the the desired level of UVLO and its hysteresis. With IHYS it is more or less clear,…
Hi,
I think when the LMR14030 goes into current limit, the frequency will foldback as you mentioned.
As the boost converter is shorted the VOUT of LMR14030 should collapse down unless there is resistance in between the output of LMR14030 and the input…
Part Number: LMR14030-Q1 Hello team,
A customer asks about the oscillation of SW node waveform in DCM mode.
Can you provivde the description in detals about why it happens?
Thanks,
Sam Lee
Part Number: LMR14030 Other Parts Discussed in Thread: TPS54360B , LMR33630 Hi team,
Could you please suggest a p2p device with LMR14030. My customers are using LMR14030 and want a back-up solution.
Part Number: LMR14030 Hi Everybody
I am using LMR14030, which corresponds to multiple input voltages, but enable pin voltage is fixed at 12V. I tried to look in the datasheet but there is no relationship between VENB and VIN Can I use it in case the…
Part Number: LMR14030-Q1 Other Parts Discussed in Thread: LMR36506 , LMR36503 , LMR43610 Hello E2E,
Our customer system input voltage is 9V - 36V, and the output is 4.5V, working current is 70-300mA, light load standby current is 2mA. What is the efficiency…
