Part Number: LMR33640
Hi,
I would like my math to be reviewed as a mistake is easily made.
My goal is to have a voltage DAC control the LMR33640 between +8V and +24V with an input voltage of 24.3V. The DAC can output between 0 and 2.048V and can sink…

Hello.
About LMR33640, at page 21/44 of the datasheet is shown this equation.
My question is about the value of Cout. For example, if I am going to use 3x 22uF (22uF nominal) ceramic capacitors at output. Then at the equation should…
Part Number: LMR33640 Hi expert
could you please help review the schematic of LMR33640, it's used on the STB, the actually output is 12V 2A
the inductor parameter: I sat =10A，I_TEMP=6A, DCR=44mohm.

Hi,
I have the question regarding PSpice simulation of 24V to 15V power supply design. Based on the project on WEBENCH:
I created the project in Pspice:
but with the simulation I am not able to achieve 15V output voltage. Can you recommend changes in…
Part Number: LMR33640 Hello,
I would like a helps about PSpice, I went to the PSpice forum but the delay is too long and I have to move forward. So I have a file (a simulation file that works very well). But When I try to simulate myself I'm having a…
Part Number: LMR33640 Other Parts Discussed in Thread: LMR51440 Hi all, I need to build a buck solution with 14.4V IN and a variable output from 3V to around 13.5V 3A. I thought about using a LMR33640ADDAR because of the low cost and because it's sync.…
Part Number: LMR33640 Hello team,
I received a question from the customer.
Could you please explain the calculation process for the highlighted areas?
VIN：***V，VOUT：***V，fsw：***kHz，K：***，IOUTmax：***A
For example, the following calculation results in…
both is ok, I suggest use both capacitor to decrese the input ripple. the input rippple is related to ESR and input power, so low ESR capacitor is recommend.
and in the same time, it also need to provide power, so we need put 47 uF to 100 uF capacit…
Part Number: LMR33640 Other Parts Discussed in Thread: TPS5420 , TPS54331 Hello,
Our customer is looking for a DCDC converter to meet following spec, and found out LMR33640 is the best. However I do not know LMR33640 can support wave soldering. Could you…
