Part Number: LMR60440

Tool/software:

Dear *,

we wan to use LMR60440 but currently we can't find the part in WEBENCH to do the simulation.

Vin =24V

Vout =8V

Iout = 3A

L = 3.3uH XGL4020-332ME

Can you provide the efficiency graph from 0.5A to 3A for the upper parameters

Fsw should be adjusted in order to use upper inductor and have max efficiency.

Hello

The best way to determine the efficiency is to use a TI EVM and measure under your exact conditions.

Thanks

Hi Frank,

thank you for the info, but we would like to do some comparisons before choosing a device.

Currently we are using TPS62933PDRL but we need a device that has VIN=36V and Vin(absolute max) at least 40V

What device would you recommend?

The TPS62933PDRL has following efficiency on 8V out and 24V in @ 1.2MHz and 3.3uH inductor
