Output Overvoltage Protection

The output overvoltage clamp consists of control cir-

cuitry, independent of the primary regulation loop, that

monitors the voltage on the output terminals. The con-

trol loop of the clamp has a higher voltage set point

than the primary loop (see Feature Specifications

table). This provides a redundant voltage control that

reduces the risk of output overvoltage.
