TPS 65023BRSB sequencing for DM368

HI,

Thanks for the interest in PMU solution for your application.

First, the TPS650061 has already been paired with the DM368. See app note: www.ti.com/.../slvu730.pdf

- It does meet the power up and down requirements. The app note walks through the design.

Second, the TPS65023 or TPS6505x can be used to power the DM368 but, would be more than what is needed for the DM368.

Also, for help to identify the best PMU for an application please check out our search tool: www.ti.com/.../power-management-multi-channel-ic-pmic-solutions-quick-search.page

Thanks for the reply.

I failed to mention in the original post that the power solution is for DM368+peripherals.  We cannot use TPS650061 as the current requirement exceeds 300mA provided by LDOs.

Both TPS65023 and TPS650532 matches the requirements (TPS650523 has better internal reset management but I2C is not needed).

I actually selected TPS65023 from the PMIC search page you have linked.  For DM368, it shows only TPS65023 and TPS650532.

Would you suggest implementing the sequencing circuit from the TPS650061 app note here or is an external sequencer IC better?
