RT6585A 20 pin qfn equivalent.

[Francisco.s]

Hi,
need an equivalent for the Richtek regulator RT6585A.
(Dual-Channel Synchronous DC/DC Step-Down Controller
with 5V/3.3V LDOs)

Perhaps a TPSxxxx?

Thanks for your help.

Looks like TPS51225, try to compare datasheets.

Thanks zpi, it looks like TPS51225 could be an equivalent, I will tray and let you know.

By the way, seems that there are RT6585A re-branded, I received some of them with smd marking code 3H=, ant those have 28 pins instead of 20.

RT3601EA also bears marking code "3H=", but it's in a QFN-28 package instead of QFN-20 package.
With Richtek ICs you have to match both the marking code and the package type.
