Forum Post: RE: TPS622318 SIMULATION

Hi John,The D/S has graphs for 1.2Vout, so this is close enough for you to get the idea.  If you want higher, you'll need to use a higher current part like TPS62080.

Forum Post: RE: Is this really the Iq for the TPS62260?

Usually the lower Iq current specs are with the device in PFM mode not switching. The spec you referred to is with the device in PWM mode, switching.I just escalated the DDR4 post with the BU.
