MAX8836Z 1.2A PWM Step-Down Converter in General Description
... Thermal shutdown limits total power dissipation in the MAX8836Z. If the junction temperature exceeds +160°C, thermal-shutdown circuitry turns off the IC, allowing it to cool. The IC turns on and begins soft-start after the junction temperature cools by 20°C. This results in a pulsed output during co ...
