TPS62442: output current capability

Part Number: TPS62442

Tool/software:

Hi Expert,

From the datasheet and other E2E threads, looks like each channel of the TPS62442 can output 3A, the sum of the two channels' current needs to be less than 4A, right? However, I would like to know, is the total current limited to 4A due to thermal limitations? If the heat dissipation conditions are good, can it support two 3.3V to 1.2V/2.5A? 

Regards,
Hailiang

  • Hi Hailiang,

    Yes the total current should be less than 4A due to thermal limitations. More than 4A hasn't been validated and it won't be possible to guarantee values outside the datasheet spec.

    Best regards,
