Part Number: LMR43610

Tool/software:

Hi，

Question 1: The input voltage of LMR43610 is 15V, the output voltage is 1.8V, and the load current is about 100mA. What is the approximate efficiency?
Question 2: The input voltage of LMR43610 is 15V, the output voltage is 3.3V, and the load current is about 10-50mA. What is the approximate efficiency?
Question 3: The input voltage of TPS62842DGRR with an input voltage of 3.3V and an output voltage of 1.8V and a load current of 100mA. What is the approximate efficiency?

Thanks!

    For VIN = 15V, the efficiency would be right in-between VIN = 12V and VIN = 18V. As you can see below the efficiency can be approximated to roughly 90%
