7.4.1 Device Functional Mode Comparison

Table 7-1 shows the conditions that lead to the different modes of operation. See the Section 6.5 table for parameter values.

Table 7-1 Device Functional Mode Comparison
OPERATING MODE PARAMETER
VIN VEN IMID_OUT IOUT TJ
Normal operation VIN > VOUT(nom) + VDO and VIN > VIN(min) VEN > VEN(HI) IMID_OUT < IMID_OUT(max) IOUT < IOUT(max) TJ < TSD(shutdown)
