Part Number: LMR12020 Dear Team,
I am using LMR12020 in my design with below mentioned conditions,
As per datasheet I calculated the inductor value as 38uH
Same way I provided the web bench input as above conditions for circuit,
But I…
Part Number: LMR12020 Hi,
MR12020 was designed to take 12Vin and output 10V out @ 0.5A. Not sure the picture is visible
We measured Vin = 11.96V, VEN = 11.5Vm VFB=0.34(clearly not working) and Vout = 3.49V
All components measure correctly. Circuit…
Part Number: LMR12020 Other Parts Discussed in Thread: TPS62173 , , TPS629210 , TPS62901 A design that previously used TPS62173 was updated to use LMR12020 due to supply issues with the original part.
A design feature of the board is that it can be…
Other Parts Discussed in Thread: LMR12020 I have questions about LMR12020.
Question 1.
Does this IC have eco-mode?
Question 2.
Do you know the IC that meets the following conditions?
Vin=15V
Vout=5V
Iout=2A
Forced PWM
Non synchronous…
Hi Akshay,
Our side already solve the problem.
Thanks for the assistant provided.
The boost function control the internal NMOS control switch.
As your connection is where the Vboost is derived from the input voltage Vin.
In order to properly…
Other Parts Discussed in Thread: LMR12020 Hi,
I am using a LMR12020 with a dual voltage ouput. Now I would like to control the output using a DAC which would be MCU controlled.
The module adjust its ouput so that the FB pin always sees 1V. Lets say…

Working with the customer on the LMR12015 and LMR12020 and they have requested Altium Designer CAD files for these devices. At a minimum, they need the Altium schematics…
Hi Yamashita-san,
I received the LMR12020 evm, and measured the dimensions. The suggested connector, 305-012-500-202, should be the correct one.

Due to the global shortage of semiconductors we now have to replace our DCDC regulator. We will not get the regulator used till now (not a TI regulator…
Other Parts Discussed in Thread: LMR14030 , LMR12020 Hi
We are going to calculate the power loss of LMR14030.
The power loss is calculated by the sum of Pcond and Psw and Pq.
Pcond = Iout^2 x Rdson x Duty.
Psw = VIN x Iout x Fsw x Tr
Pq = VCC…
