Part Number: CC1310 Other Parts Discussed in Thread: TPS54302 Hello Team CC1310,
My customer is planning to use the TPS54302 switcher ( www.ti.com/.../TPS54302) as the 3.3V power supply for the CC1310.
The TPS54302 is a "4.5-V to 28-V Input, 3-A Output…
Part Number: TPS54302EVM-716 Other Parts Discussed in Thread: TPS54302 Hi,
1. My customer used TPS54302EVM test (no change, all using EVM original setting), they found static load but switching Frequency is shift around 360kHz~400kHz,
Is it normal…
MAX16993 is a 3ch DC to DC converter. CH2 and CH3 are cascaded from CH1. TPS54302 is a single channel buck converter. I need three supplies and need adjustable switching frequency function.
BTW, I cannot find LM53535-Q1 from TI website.
Thanks!

Hi,
By itself the LMR23625 should be ok. But the TPS54302 FB reference voltage is different than the LMR23625 FB voltage therefore i dont think the TPS part will regulate at 5V
Thanks

Hey John,
The LM27341 is one of the few LM parts I support. Unfortunately I don't have a starting point for you with this part or another since I haven't simulated it before. What I would recommend doing is opening up one of the transient reference…
Hello Anthony,
thank you again for the response. Our distributor doesn't seem to have any of the products available to sample. The lead times are all around 30 weeks!
The TPS54302 seems to be a good choice too. The switching frequency is 400 kHz…
Part Number: TPS54308 Other Parts Discussed in Thread: TPS54302EVM-716 Hi.
I'm have some of the same issues as https://e2e.ti.com/support/power-management/f/196/t/858796 , however I'm only doing a single supply. 4,5V-26,4V to 3,3V.
I followed the…
Hi Dean,
Due to minimum off time limitation, there is always an allowed maximum duty cycle given a fixed switching frequency. For example, the minimum off time of TPS563201 is 220ns(which you can find from datasheet), the maximum duty cycle can be approximated…

I used the Webench design tool. The lowest total BOM cost was to use LM25011 for both 5 V and 3.3 V rails. Total BOM cost was $1.79 + $1.82 = $3.61. This is a little higher than your request of $3.00, but Webench bases the BOM cost…
