Q: DM8148 power supply 5V solution by 805721

Hello,
I have a customer working on STB concept with DM8148, they are interested in cheap power supply design for DM8148 (from 5-5.6V)
Are any recommendation for powering DM8148 already available? (reference design?)
Is any PMU recommended for DM8148? Or is anything planned?

We don't currently have a reference design nor do we have one planned for the DM8148. 

However, the TPS65023B is a potential solution with Vin from 2.5V to 6V, three DCDC switching converters and two LDOs. I don't yet know much about the power requirements for the DM8148 but from what I can tell it needs at least 3.3V, 1.8V and 1.2V all of which the TPS65023B can provide.
