Figure 32. Adding a comparator on the BO pin offers a way to latch-off the controller.
In Figure 32, Q1 is blocked and does not bother the BO
measurement as long as the NTC and the optocoupler are
not activated. As soon as the secondary optocoupler senses
temperature, Q1 base is brought to ground and the BO pin
goes up, permanently latching off the controller. Figure 33
depicts the converter behavior in case of total latch-off.
an OVP condition, or the NTC reacts to a high ambient
Figure 33. If the BO pin is lifted up to VLATCH, the controller permanently latches off.
