line regulation
(1)
VIN is compared to the programmed output voltage (VOUT). When VIN–VOUT falls below VTH_100- , the device enters 100% Mode by
turning the high side MOSFET on. 100% Mode is exited when VIN–VOUT exceeds VTH_100+ and the device starts switching. The
hysteresis for the 100% Mode detection threshold VTH_100+ - VTH_100- is always positive and 50 mV(typ.)
