Part Number: LMR38020 33_220_1p_85.pdf This is my circuit schematic diagram, reducing the voltage from 48V to 15V. At normal temperature(25℃), it can start normally at full load (1A)within 4ms. However, at -40℃ and with a power supply of 48V, it can only…
Part Number: LMR38020 Hello,
I'm thinking to use the LMR38020FDDAR to invert +18 V to -18 V with an expected current draw of about 400 mA (typ), 850 mA (max).
How much capacitance do you recommend I use on the input of the IC, specifically from VIN…
Part Number: LMR38020 Hey,
In the LMR38020 datasheet, there are two layout options mentioned:
DDA0008B – Example Board Layout
DDA (R-PDSO-G8) – Land Pattern Data
How can I determine which one I should use for my design?
Part Number: LMR38020 Tool/software: Hello TI team,
The customer requires the CB report for IEC 62368-1 of LMR38020. Please kindly assist in providing it.
Thanks
Part Number: LMR38020 Tool/software: Hi Team
Customer has a new request: input 50V tp 60V, output is 12V and Iout_max=2A, Tmax=50℃.
I chose LMR38020 as the solution but I am afraid the thermal performance on 50℃，I do a simulation on webench and the…
Part Number: LMR38020 Other Parts Discussed in Thread: LM5085 , , STRIKE , LM5168 , LM5164 Tool/software: Hello,
i did a new design with LMR38020 in replacement for the LM5085.
The new design works fine!
But now customer did an emc surge test and…
Part Number: LMR38020 Tool/software: Hello,
I want to drive the output of the LMR38020FSQDDARQ1 IC at 3.3V by supplying 24V to its input, but I’m seeing an output voltage around 1.6–1.7V. I couldn’t find any issue with the feedback resistors in the…
Part Number: LMR38020 Tool/software: Hi guys,
I've attached two different layouts for LMR38020 at 3.3V 0.5A output
If i reduce the width of the switching track in design 1, can it be used ?
The test pcb will be 4 layers - 2oz…
Part Number: LMR38020 Hi, We having a question about the different references of the LMR38020. - LMR38020 S DDAR => spread spectrum version - LMR38020 FS DDAR => FPWM + spread spectrum version - LMR38020 F DDAR => FPWM version We using the LMR38020 S…
