Question Are there any layout considerations when designing in the ADP5052? Answer Since the buck operates up to 1.4MHz it is important to follow some important
rules when designing the PCB layout. In…
Question Can the 4 bucks run at different frequency? Answer No. the 4 bucks would run the same switching frequency by external RT resistor
setting or synchronization with input clock.
However, additional…
Question Can you supply PVIN1, PVIN2, PVIN3, PVIN4 and PVIN5 independently? Answer PVIN1 supplies an internal housekeeping circuit and must be tied to input
voltage. PVIN2 and PVIN3, PVIN4 can be independently…
Question Can you use an inductor not specified in the datasheet? Answer In general yes, although it is important to evaluate the characteristics of the
inductor considered. The DCR (DC resistance) will…
Question I’m interested in using the factory fuses of the ADP5053. Can you provide me
with further information/documentation on that topic. Can these fuses be
programmed only by the Analog Devices…
Q
How can I disable one channel when I don’t’ use it?
A
If you don’t use one channel, for example dummy Channel 4, pull PVIN4, EN4, COMP4 and FB4 pin to ground, and leave SW4 and BST4 pin floating…

Question How to handle the sequence in ADP5052? Answer Each channel in ADP5052 has individual precision enable with 0.8V accurate
turn-on threshold, which allows one channel’s output can be tied to other…
Question Is it possible to order a version with factory programmed output voltages? Answer No, the ADP5052 is offered as adjustable output as default version. Refer to
the ADP5052 datasheet for available…
Question Could you please advise, what is ADIs preferred PMIC solution for Altera Arria
10 FPGA. Answer Unfortunately the datasheet is still preliminary and we would need to know
which version and…
