OPERATIONAL EXPLANATION (Continued)
<EN / CE Pin (Continued)>
In stand-by mode, the above input current can be reduced by connecting a pull-up resistor between V
ROUT
and V
DOUT
.
Note that as the XC6413/14*E to K types of the XC6413/14A to D series are ' High Active / No Pull-Down' and XC6413/14*R
to U types of the XC6413/14A to D series are ' Low Active / No Pull-Up', operations will become unstable with the CE pin
open (See the chart below).
We suggest that you use this IC with either a V
IN
voltage or a V
SS
voltage input at the EN or CE pin. If this IC is used with
the correct specifications for the EN or CE pin, the IC will operate normally. However, supply current may increase as a
result of through current in the IC's internal circuitry if a voltage other than V
IN
or V
SS
is applied.
<Toggle Operation>
The XC6413/14 A and B series have a built-in toggle ON/OFF switch which repeats an on/off operation via the EN pin's
leading edge signal when the EN logic is HIGH active, and via the EN pin's falling edge signal when the EN logic is LOW active
(Please also refer the figure below). The EN input signal duration should be over 500nsec. If the EN input signal is less than
500nsec, it is possible that the circuit fails to respond and the toggle function does not operate. To operate the toggle function
properly when the EN pin voltage noise is large, a RC filter should be used to reduce the noise in the signal to the EN pin.
XC6413/14B series can reset FF (flip flop), used for the toggle operation, internally by using a signal of the detector function.
The signal of the detector function resets FF after converted to 1 shot signal in the IC. The regulator block start to output
when a signal is given via the EN pin again.
