LM5122: LM5122 BOOST APPLICATION

aiwen chen

Part Number: LM5122

1、Can the above circuit realize an environment of 48V to 90V with an output power of 1KW? The current needs to support 30A。

2、We need to design a boost power module for solar cell charging, which needs to be boosted from 48V to 90V, with a current of about 30A and a power of 1KW，Are there any other reference designs?

Hi Aiwen,

thank you for using the E2E forum.

When targeting in output power of 1kW you need to go with a multiphase design.

Below reference designs might be a good starting point:
