Temperature Shutdown

The NCP12400 includes a temperature shutdown

protection with a trip point typically at 150

°C and the typical

hysteresis of 30

°C. When the temperature rises above the

high

threshold,

the

controller

stops

switching

instantaneously, and goes to the off mode with extremely

keep the TSD information. When the temperature falls

below the low threshold, the start−up of the device is enabled

again, and a regular start−up sequence takes place. See the

status diagrams at the Figure 44.
