Other Parts Discussed in Thread: TPS62903, TPS62135
Hi Team,
I would like to double check with you that the quiescent current of TPS63710, is it 15mA but not 15uA? Thanks
Sincerely
Frank

Hi Frank,
The datasheet is correct with 15mA typ. This is not low Iq device.
Thanks,

Hi Nancy, Amod,
Thanks for the comment, do we have another option for the inverting converter with lower quiescent current?
Vin=3.2V-4.7V
Vout= -0.8~ -4V(typical -2.5V)
Iout=1A/2A
Sincerely
Frank
Frank,
You can check TPS62903 and use it in IBB configuration. The device has low Iq. You can refer to: www.ti.com/.../slvafb4.pdf. however, it is likely you will not be able to meet the 2A condition with the -4V condition at minimum VIN with the TPS62903. You may also look at TPS62135 or possibly even higher current devices to meet the 2A condition but they will not have low Iq.
Thanks,
Amod
