Need suggestions on Low Footprint PMIC

Other Parts Discussed in Thread: LP8758-E0, LP87564-Q1, TPS65400, TPS6521815, TPS65262-2, TPS6593-Q1, TPS6594-Q1

For my camera requirement i have been using a PMIC from different OEM, due to obsolescence, i am in search of alternative.

I have spent so much time filtering on TI site but could not freeze the best suitable , below are the requirements, kindly help

Ch1 : 1V/3A

Ch2: 1.35V/2A

Ch3: 3.3V/2.5A

Ch4: 1.8V / 2.5A

Ch5(Switch):300-500mA

Ch6: 3.1V / 200mA for RTC

Switching Frequency of Bucks in PMIC 1.5 MHz

Min Input : 4V, Max Input 6V, Nominal 5V

Better if it has internal sequencer , if inbuilt sequencer is not present, i would populate a external sequencer.

(My suggestion is if we have WEBENCH like tool for PMIC it would be great)

    Hi, Mr. Daram,

      I'd like to give LP8758-E0 as an option; it has 4 bucks' outputs with sequencer and voltage setting by OTP (One Time Programmable); it has no ch5 and 6; it requires minimum business size to start a new OTP. If you think it's good for your project, please contact your TI local sales to start the process.

    Hi Shyam,

    Phil asked me to take a second look in case he overlooked anything.

    As noted, LP8758-E0 has the 4 high current bucks and 5V input, but misses the load switch, RTC power, and is not user programmable. LP87564-Q1 is in a similar situation but in a QFN package if that is preferable. TPS65400 is hardware configurable 4 bucks, but still missing load switch & RTC.

    TPS6521815 is user programmable and could support the RTC, but the buck current levels are lower than requested.

    TPS65262-2 is hardware configurable but a bit low on current as well as missing a buck, an LDO, and having no sequencing.

    Lastly, TPS6593-Q1, a user configurable version of TPS6594-Q1 without the functional safety, is targeted to be on the web by end of January and could likely support the need though it is a bit overkill.
