Using the LTM8033 as a DCDC converter for negative output voltages

Thread Summary

The user inquired about using the LTM8033 uModule in a similar configuration to the LTM8022 for negative output voltages. The final answer confirmed that while the LTM8033 can be used in such a configuration, it cannot deliver the specified 3A current and would require paralleling multiple units. The PSRR and noise characteristics are expected to be similar to those specified in the datasheet for positive voltages, but the inverting configuration is inherently noisier due to discontinuous output current.

Dear All,

Can the LTM8033 uM be used in a similar configuration as e.g. the LTM8022 on p. 15 in LTM8022 datasheet?

Will the LTM8033 be able to deliver the specified 3A current? What about PSRR and noise? do they differ from what specified in the datasheet for positive voltages?

Best Regards
