Programming Output Voltage and OVP
The EN5336QI output voltage is programmed using a simple resistor divider
network. Figure 2 shows a schematic view of the resistor divider configuration.
The evaluation board uses a trim pot in place of resistor Ra1.
The EN5336QI output voltage and over voltage thresholds are determined by the
voltages presented at the XFB and XOV pins respectively. These voltages are
set by way of resistor dividers between V
to XFB and XOV.
It is recommended that Rb1 and Rb2 resistor values be ~2kΩ. Use the following
equation to set the resistor Ra1 for the desired output voltage:
