PRODUCTION DATA.
When the EN pin is pulled low for 1 ms, the IC stops the PWM switch and turns off the isolation switch, providing isolation between input and output. The internal current path consisting of the isolation switch’s body diode and several parasitic diodes quickly discharges the output voltage to less than 4.3 V. Afterwards, the voltage is slowly discharged to zero by the leakage current. This protects the IC and the external components from high voltage in shutdown mode.
In shutdown mode, less than 1 μA of input current is consumed by the IC.
