Please let us know TPS63061 Vout accuracy when VPS/SYNC=Vin.

I only found  Vout accuracy when  VPS/SYNC=GND in datasheet Page5.

    Looking at Page 10 of the datasheet, it seems the output voltage during PFM has a fixed hysteretic swing(turned on/off) based on a comparator's threshold as the converter actually stops operating at low loads. During regular operation at loads >100mA, the device is in PWM mode and the Vout accuracy depends on the device's voltage ripple which is dependent on the frequency of the device, output capacitance, etc.

    This should be the same 1% accuracy as the adjustable TPS63060 IC.
