TEST CONDITION
V(VDRP) – V(DACBUFF) = 1.67 mV
(OC Delay post power-up)
With FB = 0V, adjust V(SS/DEL) until
EAOUT drives high
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5V≤ V(VOSEN+) - V(VOSEN-) ≤ 1.6V
0.5 V < V(VOSEN+) < 1.6V
-0.3V ≤ VOSEN- ≤ 0.3V, All VID Codes
V(VCCL) – V(VO)
V(VCCL)=7V
Measure V(FB) – V(VSETPT). Note 2
R
Note 1
Note 1
Measure V(VCCL) - V(EAOUT), Relative
to Error Amplifier maximum voltage.
Measure PHSOUT pulse numbers from
V(EAOUT) = V(VCCL) to VRRDY = low.
ENABLE rising
ENABLE falling
0V ≤ V(ENABLE) ≤ 3.3V
Noise Pulse < 100ns will not register an
ENABLE state change. Note 1
