MC34VR500 Power Consumption Calculation

TJAhn — Wed, 19 Jun 2024 11:13:26 GMT

Hello,

I'm trying to calculate power consumption estimation of MC34CR500 in my project.

In the datasheet, I can see the power efficiency with SW1~4, but only with fixed input voltage.

I'm figuring out how to calculate power consumption of SW1~4 and LDO1~5, and VREFOUT.

My question is this:

How can I calculate estimation of MC34VR500 power dissipation with 3.3V Voltage Input?

Best Regards,

Thanks for answer, but I already checked datasheet.
What I want is to check the efficiency figures of SW2~SW4, and LDO1~5 when VIN=3.3V.
Is there another way to calculate? Is there tools about it? Any other AN?
