160°C the device does not start switching. The device re-
starts switching when the temperature drops more than
15°C (typ.) but the MODE settings are not re-loaded again.
If the temperature continues to rise and above LDO thermal
shutdown threshold (T
SD_LDO
, typically 171°C), the
converter shuts down completely.
Note that the over temperature protection is intended to
protect the device during momentary overload conditions.
The protection is activated outside of the absolute
maximum range of operation as a secondary fail-safe and
therefore should not be relied upon operationally.
Continuous operation above the specified absolute
maximum operating junction temperature may impair
device reliability or permanently damage the device.
Output Voltage Discharge
An internal 500Ω discharge switch that discharges the
V
OUT
through SW node during any fault events like OVP,
UVP, OTP , VCC voltage below UVLO and when the EN
pin voltage (V
EN
) is below the turn-on threshold.
