Posted by: vijay.kapse@ea… on

Currently we are using some top switched in our power supply like TOP104YN, TOP224 & TOPP224, I need clarification on this

1. What is current status of Lifecycle of all above ICs.

2. If EOL then any equivalent with pin compatible is available or not?

3. Please suggest new IC for new design w.r.t above ICs.

Please treat this is very urgent because our current product is held up due to this IC

 Hi,

 

PLS see my answers below.

 

1.  TOP104 has been obsoleted already. For TOP224,we do not have any plan to obsolete it right now.

2. TOP104 and TOP224 are very old, for new parts of TOP family,  PI donot have equivalent with pin compatile.

3.  For current limit point of view,TOP265 is close to TOP224, and TOP270  is close to TOP104. Using PI expert, it is much better and easier to identify the best replacement.  You can download PI expert at PI website, and choose top jx family when you run the calculation. TOP jx is the newest part for TOP switch.

 

Thanks a lot for using PI part, and really sorry for no drop out replacement.

Can anybody suggest equivalent of Top 414. I know it is obsolete long back.
Thanks & Regards
Sanjay

Hi Sanjay,

 

There is no pin-to-pin replacement for the TOP414.  The closest replacement would be the DPASwitch family, but it is not pin-to-pin compatible.
