This is the most negative power supply input. All pins except DISABLE are referenced
to this input.
This is an active high power good output signal. This pin is referenced to VIN.
This is an active low power good output signal. This pin is referenced to VIN.
This pin is the drain of the internal Power MOSFET and supplies a current limited voltage
to the load.
This input is used to control the time base used to generate the timing sequences at
start-up and the retry delay when the device experiences any fault.
Not connected.
This pin is used to set the upper limit of the input voltage operation range.
This pin is used to set the lower limit of the input voltage operation range.
This is the most-positive power supply input. The load connects between this pin and the
VOUT pin.
This pin is used to easily disconnect or connect the load from the main power line by
disabling or enabling the 34652. It can also be used to reset the fault conditions that
cause a “Power No Good” signal. This pin is referenced to VPWR.
This pin is used to set the overcurrent limit during normal operation.
This pin is used to set the load’s input capacitor charging current limit, hence limiting the
inrush current to a known constant value.
