TPS51275C: Is there output current limit for this part?

Aki Li

Part Number: TPS51275C

Customer wants to use this part in their PC application, and not sure whether there is limitation for the output current. Can it push to 20A for each output?

Aki,
yes, TPS51275C has OCP function, refer datasheet page 14 and equation 4.
Also, the device can support 20A for each output.

Jason,

Thank you. Besides, in the datasheet, does the output voltages: 5 V and 3.3 V refer to CH1 and CH2 switching frequency of 300KHZ and 355KHZ, respectively?

Hi Aki,

Yes, 300kHz is for CH1 (5V Vout), and 355kHz is for CH2 (3.3V Vout).

Regards,

Hao
