13. REMOTE OUTPUT ON/OFF CONTROL
The converter output can be enabled or disabled through the On/Off pin. The control logic is shown in this table. A common control
circuit is shown below.
14. ISOLATION
The input and output of the converter are electrically isolated. If needed, an output terminal can be connected to an input terminal,
resulting in the converter non-isolated.
15. INPUT FILTERING AND EMI INTERFERENCE
The VHB200W converters have input capacitors that control input current ripple and the associated EMI interference. However, it
has not been tested to a formal standard for conducted emissions. Additional filtering may be needed to ensure compliance to an
EMI standard. Refer to FIGURE 10 for a reference circuit.
