Note 1
Note 1
VBIAS–VEAOUT (referenced to VBIAS)
Note 1
-0.3V ≤ VOSNS- ≤ 0.3V, Connect FB to
EAOUT, Measure V(EAOUT) –
V(VOSNS-) deviation from Table 1.
Applies to all VID codes.
0V ≤ VID0-5 ≤ VCC
Measure from VID inputs to EAOUT
V(EAOUT) – V(DAC). Applies to all VID
codes from table 1 and -0.3V ≤ VOSNS-
≤ 0.3V. Note 2
Normal operation or Fault mode
V(VDRP) – V(IIN), 0.8V ≤ V(IIN) ≤ 5.5V
Note 1
Difference of preconditioning active
voltage and SS/DEL-FB offset voltage
SS/DEL=0V.
