<Toggle Operation>
XC6413 series has 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). Please input EN input signal more
than 500nsec. If the EN input signal is less than 500nsec, there is the case that the circuit falls to respond and the toggle function cease to work. To
operate the toggle function properly, please eliminate the noise from EN signal by using RC filter, etc. A flip-flop FF used for toggle operation can be
reset within the XC6413B series directly by the signal from the voltage detector. The signal of the voltage detector will be transformed to one-shot signal
to reset FF. The voltage regulator output when the EN pin release the signal again.

NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current.
Please strengthen VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
In case that rapid input fluctuation or load fluctuation are occurred, please enlarge capacitor value such as CIN or CL
to stabilize the operation.
