TPS54626: Upgraded P2P alternative

Hi Itoh,

Sorry, we don't have P2P for TPS54626.

If customer can accept non-P2P solution, TPS51397A (10A) and TPS568230 (8A) may be suitable.

Thanks,

Lishuang

Hello Lishuang-san,

Non-P2P solution is accepted.

Is TPS51397A pin compatible to TPS568230?

Itoh

Hi Itoh-san,

Yes, TPS51397A and TPS568230 can be pin compatible. But I want to emphasize more points:

1. TPS568230 Vin max is 18V. TPS51397A Vin max is 24V.

2. Non-latched for fault protection of TPS568230.  Latched output OV and UV, non-latched UVLO and OT protections of TPS51397A.

3. One is frequency setting, or the mode pin configuration. TPS568230 has three frequency setting, 600KHz, 800KHz and 1000KHz while TPS51397A has 500KHz and 800KHz. Details can be checked in Table 1 on DS.

4. The other is the thermal pad difference. TPS568230 has 0.76*0.675mm2 thermal pad while TPS51397A has 0.975*0.926mm2. But they can be co-lay.

Thanks,

Hi Lishuang-san,

Could you please send me the package outline information of TPS568230 to design the co-lay pad?

It is missing from the datasheet.
