OPERATIONAL EXPLANATION (Continued)
<EN Pin>
The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6402C series. In shutdown mode, output at the VROUT
pin will be pulled down to the VSS level via R1 & R2. Note that as the XC6402*E to K types of the XC6402C series are 'Active HIGH / No Pull-Down' and
XC6402*R to U types of the XC6402C series are 'Active LOW / No Pull-Up', operations will become unstable with the EN pin open (See the chart below).
!
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.
Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as CIN or CL
to stabilize the operation.
XC6402C R ~ U
Active LOW with no pull-up resistor
We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the EN pin. If this IC is used with the correct specifications for the EN
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
VIN or VSS is applied.
