voltage. When the programmed value of the output voltage is
less than 5% of full-scale, the OVP threshold will be set to a
fixed minimum value of 5.5% of full-scale.

In the event of a trip condition, the voltage at the output
terminals is reduced to less than the programmed set-point at
a rate of V

/20ms, and to less than 1% of full-scale, plus
1V, within 20ms. An active downprogrammer discharges
output capacitance.

VERVOLTAGE
(ROVP)
Tracking redundant overvoltage protection set at 120% of OVP value, or 3V
above OVP value, whichever is greater, measured at the output terminals.
Shorted or reversed sense leads will result in redundant overvoltage
shutdown.
O
VERCURRENT
(OCP)
The OCP operation is user selectable to be programmable or tracking. The
default mode of operation is programmable OCP.
•
Programmable operation: The OCP threshold is
programmable from 5 to 120% of full-scale output current.
•
Tracking operation: The OCP threshold is automatically
adjusted to 120% above the programmed value of the output
current. When the programmed value of the output current is
less than 5% of full-scale, the OCP threshold will be set to a
fixed minimum value of 6% of full-scale.

VERTEMPERATURE
Overtemperature protection is implemented with protection monitors that
sense excessive internal heatsink operating temperature. Excessive
temperature results in shut down of the power converter and output turn-off.
