■OPERATIONAL EXPLANATION

The XC6192 series A type fixes VOUT at “H” voltage (same level as the VIN pin voltage) when “L” voltage is

input the required time into the SW pin, and shuts down VOUT (same level as GND) when “L” voltage is

subsequently input the required time into the SW pin, thereby realizing alternating ON/OFF control(*1). Two

shutdown methods are available: inputting “H” voltage into the SHDN pin, and inputting “L” voltage the

required time into the SW pin.

(*1) Alternating ON/OFF control on this IC is a system that alternates between VOUT “H” voltage and shutdown each time “L” voltage is

input the required time into the SW pin.

The B type fixes VOUT at “H” voltage when “L” voltage is input the required time into the SW pin. After VOUT

is fixed at “H” voltage, the signal is not accepted if “L” voltage is subsequently input into the SW pin. The

shutdown method is inputting “H” voltage into the SHDN pin.

As protective functions, the XC6192 series is equipped with a rush current prevention circuit and a

short-circuit protection circuit.
