PRODUCTION DATA
The device monitors internal junction temperature. If the temperature exceeds the threshold value (typically 165°C), the device stops switching and discharges the SS/REFIN pin. When the temperature falls approximately 30°C below the threshold value, the device turns back on with a re-initiated soft start. Thermal shutdown is a non-latch protection.
