Part Number: LM2840 I created a design for the LM2840X in TI Webench using the following settings
Vin: 24V
Output: 3.3V @ 0.05A
Max Ambient Temp: 85C
Webench successfully creates a schematic but when I try to simulate, only the Bode Plot simulation…
Part Number: LM2840-Q1 The frequency response of my Webench design for this switching regulator is not great.
With 5.7-15V input voltage range, output voltage of 3.3V and max load 0.04A.
The original design chosen by Webench gave phase margin of 45…
Part Number: LM2840 Other Parts Discussed in Thread: LM2841 , , LMR14203 Hello team,
My customer is considering use LM2840 as an alternative for LM2841 due to the current situation.
In this, we should check two points. Can you give me your thought…
RE: LM2840: LM2840 short circuit protection? Vin = Vout after shorted output to ground Hi Daniel, great thanks for the answer. I changed the hole layout. is the new layout better in your opinion? Thanks a lot for the answer!
Part Number: LM2841 Other Parts Discussed in Thread: LM2840 , LM2842 Hi,
we have implemented an inverting power supply design using the LM2840YMK-ADJ by following the guidelines in your application note SLVA317B. This circuit works fine. Our input voltage…
Part Number: LM2840 Hi team,
I’m thinking of using it with 24V input, 15V output, and 60mA draw. The theta JC value of 94 is very high. Our thermal analysis based on 0.9W, shows it over the max 150C junction temp by significant margin. Is there another…
Part Number: LM2840 I am using LM2840 to generate -3.3V. The schematics is same as the example circuit in data sheet for generating 3.3V
My question is: In the Electronic characteristics table, the Quiescent current (NO LOAD) is 1.35mA typical. In my…
Hi,
Yeah the main difference between the LM2840/41 series is the current limit trimming option. One is trimmed at higher current than the other.
Also, i believe the soft-start should work over temperature.
As for TPS57060, yes it offers more functionality…
Hi.
I've the same trouble and I've burnout 5 samples.
Looks like the L selection equation has mistakes.
I need 5 Vdc 100 mA fixed sourcing with 24 Vdc.
When the IC burns, sends 24 Vdc to the output. It's a big problem. I've burnout a microcontroller…
