PARAMETER
Note 1
Duty Cycle of GATEH2 to GATEH1
Duty Cycle of GATEH2 to GATEH1
Note 1
DTC GATEH1 – DTC GATEH2
V(SS/DEL)=0
(Internal Ramp1 Start Voltage) – (0DC
Threshold)
VCCL = 12V. Step EAOUT from .8V to
.3V and measure time to GATELX
transition to < 11V.
Compare V(FB) to V(VDAC)
VID_SEL=0V. Compare to V(VDAC)
Float VID_SEL. Compare to V(VDAC)
VCCL = 12V. V(EAOUT)=0V. Step FB
460mV above V(VDAC). Measure time
to GATELX transition to >1V.
OVP to PGND1
I(OVP)=10mA, V(VCC)-V(OVP)
