PARAMETER
Measure V(VCCL) - V(EAOUT),
Relative to Error Amplifier maximum
voltage.
Measure PHSOUT pulse numbers from
V(EAOUT) = V(VCCL) to PGOOD =
low.

0V ≤ V(ENABLE) ≤ 3.3V
Noise Pulse < 100ns will not register an
ENABLE state change. Note 1
1V ≤ V(OCSET) ≤ 3.3V
R
ROSC = 7.75 K (PHSOUT=1.5MHz)
ROSC = 15.0 K (PHSOUT=800kHZ)
ROSC = 50.0 K (PHSOUT=250kHz)
Note 1
Compare to V(VDAC)
Compare to V(VDAC)
Measure time from V(VO) > V(VDAC)
(250mV overdrive) to V(IIN) transition to
> 0.9 * V(VCCL).
Measure time from V(VO) > V(VDAC)
(250mV overdrive) to V(ROSC/OVP)
transition to >1V.
Measure V(VCCL)-V(ROSC/OVP)
V(VCCLDRV)=1.8V. Measure V(VCCL)-
V(ROSC/OVP)
OSC
= 24.5 K
