TPS610981: Low Power Mode

K.Hamamoto

Part Number: TPS610981

I have a question about Low power mode. There are some current limit at Boost SW and VSUB output.

The Boost switch current limit is included VSUB output current limit at Low power mode. Is my understanding correct?
If it so,500mA(typ) which is boost sw limit is included 200mA(min) of VSUB output limit as well.

Could you correct me if my understanding above is not correct?

Best regards,

I think you understanding is correct and this can be confirmed in a couple of days by the engineer who is an expert of this device. Currently the engineer is out of office on holidays.

yes. your understanding is correct. the SW current limits the current capability out of VMAIN. as the VSUB is also powered by the VMAIN, so the SW limit both the VSUB and VMAIN.
