Other Parts Discussed in Thread: TPS65910, TPS650006, OMAPL138, OMAP-L138, TPS650061

I am using OMAPL138 processor. What PMIC part does TI recommend for it that satisfies power and sequencing requirements? Is there a high reliability version of this part? I found these on the website: TPS65070RSL, TPS650250RHBR, TPS650006, TPS65910. I am not sure which one fits OMAPL138 better.

Hello Amit,

TI recommends to use TPS650061 for powering the OMAPL138 device. You can refer the below document for more details.

Thanks both Titus and Senthil. I looked at multiple PMIC offered by TI. The TPS650061 is a good fit. However, it doesn't provide enough margin for my application on the load current requirement of the OMAPL138. In addition the power sequencing is controlled externally by adding more circuitry to provide delay and provide enables. I will more likely use the TPS65910A1RSL. It also provides application guide for powering OMAPL138. It has enough power margins and has built in power sequencing.

Hello Amit,

Yes, you can use TPS65910A1RSL PMIC for powering OMAPL138. If you have any question about the interconnection between TPS65910 and OMAPL138, feel free to post query in power management forum. They will help you better.
