PRODUCTION DATA
The regulated output of the DCR01 can be disabled by pulling the ENABLE pin LOW. Disabling the output voltage this way still produces a voltage on the VREC pin. When using the ENABLE control, TI recommends placing a 10-kΩ resistor between the VREC and ENABLE pins. The ENABLE pin only controls the internal linear regulator.
If disabling the regulated output is not required, pull the ENABLE pin HIGH by shorting it directly to the VREC pin, which enables the regulated output voltage, thus allowing the output to be controlled from the isolated side.
