Summary of Contents for EN63A0QI

Page 1: ...The RB resistors can be chosen by jumper settings to achieve several output voltages The EN63A0QI includes the bulk of the compensation network internally However an external phase lead zero capacitor and resistor is required as part of the feedback This network is shown in Figure 1 Appropriate component values allow for optimum compensation for a given Input voltage and choice of loop bandwidth T...
