... Drive, Compensation Network, and controller and protection circuitry. This level of integration delivers a substantial reduction in footprint and part count over competing solutions. • The EN5336QI features resistor divider output voltage programming. The resistor divider allows the user to set the output voltage to any value within the range 0. ...

... STEP 4: Apply V to the board and move the ENABLE jumper to the enabled IN position. The EN5336QI is now powered up! NOTE: There is no de-bouncing circuitry associate with the enable pin. NOTE: The trim pot is set at the factory to a predetermined output voltage. To adjust to another output voltage setting, turn the screw on the trim pot while monitoring the output voltage using an accurate volt-meter ...

... 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 recommended that Rb1 and Rb2 resistor values be ~2kΩ ...

... Measure input and output current with series ammeters or accurate shunt resistors. This is especially important when measuring efficiency. 3. Use a balanced impedance probe tip to measure switching signals to avoid noise coupling into the probe ground lead. EN5336QI Evaluation Board Application Note 2 VOUT R R ...

... The output capacitance requirement is approximately 50uF of capacitance. The EN5336QI-E evaluation board comes populated with 5 x 10uF 6.3V 1206 MLC capacitors. The 5 parallel capacitors provide for reduced ESR and hence lower output ripple voltage minimum footprint configuration is desired, the 5 x10uF capacitors can be replaced with a single 47uF MLC capacitor ...
