TPS6521825: PMIC

Part Number: TPS6521825

Tool/software:

Hello,

I am designing a power supply for a processor-based board which should be PS1 class. The input voltage range will be 9v-16v and step down to 5v, 3.3v, 1.8v, 1.2v, 1.1v, 1.2v. Can someone please suggest a suitable PMIC from TI?

    Hi Jay,

    I'm not sure what this PS1 refers to? Could you elaborate that a little more. 

    Do you have more information about processor since we might have worked with similar solution previously? Also is this Automotive, Industrial or what application and are there any functional safety capabilities needed?

    Br, Jari

    Hello Jari,

    The processor we are going to use is Rockchip RK3756, which is for automotive camera applications. PS1 - "PS1 class power supply" refers to a power supply that falls under the "PS1" category within the IEC 62368-1 safety standard.

    Hi Jay,

       We have a PMIC linked here to handle the input voltage range 9v-16v and step down to 3.3v, 1.8v, 1.2v, 1.1v easily with 3 Bucks and 1 LDO total 4 rails.

       We have 3 other similar PMICs; all have only 4 power rails; we don't have existing PMIC for cameras with 6 power rails. 

    Thanks!
