TPS65185: RSL vs. RGZ

Part Number: TPS65185

Hi,

We have a product prototype that is using an EINK display. The TI part that was installed for the PMIC is TPS65185RSLR. The datasheet has another part number TPS65185RGZT (RGZ) with device marking for E INK. Is there a way for the “RSL” package to behave like the “RGZ”. Do we have to configure anything on the chip for this to happen? Please advise. 

  • Thank you for posting your question on the TPS65185 in the e2e forum. Your thread has been assigned to the expert within TI, who will reply to your question as soon as possible and attempt to answer this question to your satisfaction.
  • Candy,
    Upon quick inspection of your question, it appears you are asking about the suffix in the Orderable Part # that refers to physical packaging.

    RSL = www.ti.com/.../mpqf193a , a type of 48-pin VQFN packaging that is 6x6mm
    RGZ = www.ti.com/.../mpqf123e , a type of 48-pin VQFN packaging that is 7x7mm

    The same Generic Part Number (GPN) in different packages should behave identically with slightly different Thermal Characteristics.

    On the other hand, the TPS65185 and TPS651851 are different GPNs and therefore the TPS651851RSLR and the TPS65185RGZT have different packages and different electrical characteristics. These electrical characteristic differences are usually called out in the datasheet. For example, on the Cover page of this datasheet it says that LDO1/2 of the TPS65185 are rated for 120mA while LDO1/2 of the TPS651851 are rated for 200mA, so this is probably the most significant difference between the 2 GPNs.

  • Brian is correct, there are no functional differences between RSL and RGZ devices, but the TPS651851 will just have higher current capabilities than the TPS65185.
