Hello,

I'm searching PMU which have below function from our customer request.

I can't find detail of the PMU due to there is no datasheet on the web.

Please kindly help us...

LP3923 is close to our customer request.

However , we can't change the device default voltage.

Are there any device which has below outputs?

1.8V　200mA

3.0V　200mA　

3.3V　700mA

3.3V　200mA

Not decided specification yet.

HI Ryuji,

You can use some load switches to separate the 3V and 3.3V rails. Thus, instead of 9 rails required you only need 4. I suggest looking at the TPS6502x family like the TPS65023 or TPS650250.
