... V OUT VDDQ. • The EV1340QI includes the bulk of the compensation network internally. However, an external phase-lead (zero) capacitor and resistor is required in addition to two resistor dividers to set the output voltage. This network is shown in Figure -1. Appropriate component values allow for optimum compensation for a given VDDQ voltage and choice of loop bandwidth ...

... When the jumper is between the left and middle pins, the signal pin is connected to AVIN or logic High. WARNING: complete steps 1 through 6 before applying power to the EV1340QI evaluation board. STEP 1: Set the “ENA” jumper to the Disable Position. See Figure 2 above. ...

... CAUTION: Except ENA, no other jumpers can be changed while the EV1340QI is powered on. Doing so could result in damage to the part. STEP 4: Connect the VDDQ Power Supply to the input power connectors, VDDQ (J13) and GND (J7) as indicated in Figure 4 and set the power supply to the desired voltage (≤1.8V). For VDDQ more than 1.5V, the loop compensation values will have to be adjusted according to the datasheet ...
