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 am getting the…
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 simulated…
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 powered…

Non synchronous rectificat…
Other Parts Discussed in Thread: LMR12010 Hi,
I encounter an issue in power system design, enclose is the schematic design of LMR12010 20Vin,1A step down voltage regulator.
The issue is I can’t get the correct output voltage(3.3V) while I having 12V input…
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 I use…
Other Parts Discussed in Thread: LMR12015 , LMR12020 , LM27341 , LM27342 Hello,
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 symbols…
Hi,
Some of these parts are not available at all. Like TPS562211 which is only available as samples. TPS562201 is also not available somewhere.
How about LMR12015/LMR12020 as an alternative regulator for us? This regulator seems to be more available from…
Hi Yamashita-san,
I received the LMR12020 evm, and measured the dimensions. The suggested connector, 305-012-500-202, should be the correct one.

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 x Iq.
