TPS63070: TPS63070RNMR Low-Iq Alternative with Same Footprint

Hi Ron,

I split the original thread, since it was marked as resolved.

We do not have a low-Iq TPS63070 alternative, for input/output voltages above 5.5 V. 

Could you please confirm what are your Vin, Vout, Iout requirements? In your original thread you mentioned that your input voltage is 4 V and the output voltage is 5 V. If so, the TPS63802 would be a better match, it is in similar package as the TPS63070, but with lower Iq. 

Best regards,
Milos

Hi Milos,

Vin = 2.5~5V
Vout = 4V
Imax = 1A
Iq = as low as possiable (10uA or less) 

in the datasheets, it seems the TPS63802 and TPS63070 has a diffrent package.
TPS63802 has a "10-Pin VSON-HR" package while TPS63070 has "VQFN-15". 

Hi Ron,

The TPS63802 would fit better than the TPS63070. 

Yes, these are not pin-to-pin compatible devices. Can you still work with it? They have similar DFN/QFN packages, and similar pin arrangement, so the PCB redesign should not be too difficult. 

Best regards,
Milos

Hi Milos,

Unfortunately, a redesign is not an option right now. Do you have any other solution besides the TPS63802 and has the same footprint?  

Hi Ron,

No, sorry, we do not have a pin2pin alternative to the TPS63070.

Best regards,
Milos

Thank you, one last question:
Is the "VQFN-15" footprint a special design by TI?

Hi Ron,

We haven’t heard back so we're assuming this answers your question. If not, just post a reply below, or create a new thread if the thread has locked due to time-out.

Thanks and regards,
Milos
