Progr. Input Undervoltage Lockout PUL
A special feature of the converters (with Rev. BA or later) is the
adjustable undervoltage lockout protection, which protects
the converter (and the system) from high current caused by
operation at low input voltages. This ensures easier start-up
in distributed power systems.
The table below shows the band of switch on/off and the
hysteresis.

The undervoltage lockout levels may be programmed by using
an external resistor R PUL between PUL and Vi – to increase the
preset levels as specified in table 10.

voltage for input voltage.
