Part Number: LM2738 Dear all,
I use this design for my circuit, but I realized that when I removed D1, my board still work well.
Can you confirm that D1 is necessary or not? since I think this diode is essential for a buck topology.
Thank you,
Power …
Part Number: LM2738 Dear Power Experts,
On the LM2738YMY switching regulator part the absolute maximum voltage listed for the feedback pin is 3V.
Is this truly a voltage limit not to exceed on the pin or is it to keep the current flowing into the…
Hi Art,
Using the XRef tool on TI.com: http://www.ti.com/sitesearch/docs/universalsearch.tsp?searchTerm=LTC3408#linkId=8 , you'll see the LM2738 is a close match (but it is not a direct replacement):

Other Parts Discussed in Thread: LM2840 , LM2738 Hi!
I am designing a Dc Dc converter with LM2840 that needs to have 12 V at the output (0.1A max).
I prepare a prototype (like figure 4 of the datasheet) with the Y version of the IC for reduce inductor space…
Hi Emil,
I haven't worked with this part but here is my guess to what is happening for the no load situation.
The LM2738 is an asynchronous buck converter (uses a catch diode D1, instead of a low side fet). With this type of converter the internal…
