Thermal Shutdown

Thermal shutdown is employed in the MP8764.

The junction temperature of the IC is internally

monitored. If the junction temperature exceeds

the

threshold

value

(minimum

150ºC),

the

converter shuts off. This is a non-latch protection.

There is about 25ºC hysteresis. Once the

junction temperature drops to about 125ºC, it

initiates a soft startup.
