LTM8053 peak output current

Category: Datasheet/Specs
Product Number: LTM8053

LTM8053 is rated at 3.5A continuous output current and 6A peak output current.

I need to know how long it can provide output at 6A (peak).

Can it remain producing 6A at more than 2 hours (for example)?

Thanks,

  • As I think you don't want add extra cooling this will not work. For 2h of 6A you should use two of LTM8053 or just a bigger module.

    The mentioned peak rating belongs to the internal FETs capability and is purely intended for transient loads, With continuous use of 6A the part just gets too hot and will fail.

    Check page 21, thermal considerations and the diagrams for the current derating over temperature.
