... D3. When there is an open LED condition, the diode D3 will clamp the output voltage and the zener diode current will be regulated by the sum of R s2a Supertex inc. Damping Circuit The Ćuk converter is inherently unstable when the output current is being controlled. An uncontrolled input current will lead to an un-damped oscillation between L1 and C1 caus- ing excessively high voltages across C1 ...

... REF This pin provides accurate reference voltage. It must be bypassed with a 0.01 - 0.1µF capacitor to GND. Supertex inc. Before the design of the output side is complete, over voltage protection has to be included in the design. For this applica- tion, choose a 33V zener diode. This is the voltage at which the output will clamp in case of an open LED condition ...
