EP68 3.3 V, 2 A DC-DC Power Supply  
4.3 Output Feedback  
The output voltage is sensed via the resistor divider formed by R12 and R13 and fed into  
the reference pin of the low voltage reference, U3. Feedback compensation components  
R10, R11, and C13 ensure stable operation and optimum line and load transient  
response. Capacitor C12 provides a soft-finish characteristic, preventing output voltage  
overshoot during startup of the converter.
