The converter requires a minimum load current at either the V O Seq or V O Bus output for proper operation. The converter is not
damaged when operated under a no-load condition.
See temperature derating curves for safe operating area (SOA), to determine output current derating at elevated ambient temperatures.
When load current is supplied from the V O Seq output, the module exhibits higher power dissipation and slightly lower operating
efficiency.
The set-point voltage tolerance is affected by the tolerance and stability of R SET . The stated limit is unconditionally met if R SET has a
tolerance of 1%, with 100 ppm/°C temperature stability.
When controlling the Track input from an external source, the slew rate of the applied signal must be greater than the minimum limit.
Failure to allow the voltage to completely rise to the voltage at the V O (bus) output, at no less than the minimum specified rate, may
thermally overstress the converter.
The PEN and NEN inputs each have an internal pullup resistor. If the enable feature is not used, the PEN input (pin 2) should be left
open circuit and the NEN input (pin 3) permanently connected to –V I . A discrete MOSFET or bipolar transistor is recommended for the
enable control. The open-circuit voltage is less than 10 V. See the Application Information for a more detailed description.
