Part Number: LMR14030-Q1 Other Parts Discussed in Thread: LMR14030 , LMR14050 , LMR23630 Hi
I simulated this device with the following condition by WEBENCH. However it has an error. ( phase margin is not enough.)
Vin=6~16V, Vo=1.5V, Io=3A
My question…
Part Number: TPS25944L Other Parts Discussed in Thread: LMR14030 , , LM2596 , TPS53353
I am trying to protect my LMR14030 DC/DC converter set to 3.3V and as well the 12V bus. The protection i made on the input side of the converter using TPS25944L.The…
Part Number: LMR14030 Hi
By setting RT, switching frequency would be set.
LMR14030 can have three operation mode, CCM, DCM and sleep.
Is Fsw changed depending on operation mode?
1. For example, When RT = 11.5Kohm, switching frequency is set…
Part Number: LMR14030-Q1 Hi team,
A customer asks about how to calculate power dissipation for below snubber circuit of LMR14030-Q1.
Can you let me know the equation between R332, C315, Fs and etc?
Pd (R332) = ??
Thanks,

Part Number: LMR14030 Hi,
Our customer use LMR14030 to convert 12V to 5V, then convert 5V to 1.25V, at least 200mA as the core voltage of MCU by another DC-DC switching at about 1.2MHz. However, when MCU works, the inductor of LMR14030 has squeaking…

Part Number: LMR14030-Q1 Dear team,
Could you please help answer below questions?
1. What is the input voltage at the red arrow in the figure below? 5.4V?
2. If the output voltage is 5V, the output current is 1A, the switching frequency is 500K…
Part Number: LMR14030-Q1 Hi sir,
The LMR14030-Q1 feedback reference voltage tolerance is within 2%,but what does the following curve figure mean?
the tolerance for rising and falling under different switch frequency %? is it right?
