FEATURE DESCRIPTIONS
Output Overvoltage Clamp
The output overvoltage clamp consists of a separate control loop, independent of the primary control loop. This
control loop has a higher voltage setpoint than the primary loop. In a fault condition the converter goes into
“Hiccup Mode”, and the output overvoltage clamp ensures that the output voltage does not exceed Vo,clamp,max.
This secondary control loop provides a redundant voltage control that reduces the risk of output overvoltage.
Output Current Protection
To provide protection in an output overload or short circuit condition, the converter is equipped with current limiting
circuitry and can endure the fault condition for an unlimited duration. At the point of current-limit inception, the
converter goes into “Hiccup Mode”, causing the output current to be limited both in peak and duration. The
converter operates normally once the output current is brought back into its specified range.
Enable
Two enable options are available. Positive Logic Enable and Negative Logic Enable. Positive Logic Enable turns
the converter ON during a logic-high voltage on the enable pin, and OFF during a logic-low. Negative Logic Enable
turns the converter OFF during a logic-high and ON during a logic-low.
