TPSM82822: Compete with LTM4691

Part Number: TPSM82822

Tool/software:

Hi Team,

Do we have dual channel 2A Buck power module that can compete with LTM4691?

If not can we use two TPSM82822 to replace the LTM4691? Will two TPSM82822 in parallel support 180degree interleaving mode?

Thank you,

Yishan Chen

    Hello Yishan,

    thanks for reaching out in E2E.

    We don't have a dual channel module, but we have comparable discrete products, such as the TPS62442.

    Two TPSM82822 could be used to replace the LTM4691 but their switching frequency can not be synchronized so they would not run in 180° interleaving mode.

    The TPSM828512 or TPSM82813 would allow external frequency synchronization.

    These modules cannot be stacked to supply one output rail in parallel. I think the two outputs of the LTM4691 also cannot be stacked. If a higher output current is required then I would suggest to use a single 4A device, such as TPSM82810.

    Best regards,

    Andreas.
