˙OPERATIONAL DESCRIPTION (Continued)
<Input and Output Capacitor>
The XC6419 needs an output capacitor C_L for phase compensation. The requested capacitance values are described in the
table below. The device may go into unstable operation when the output capacitance reduction happens as a result of bias or
temperature drift. Please choose a capacitor with less influence from temperature and bias. Also, please place 1.0ЖF input
capacitor C_IN between V_IN and V_SS pins for stabilizing input supply voltage.

˙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 wire the input capacitor CIN and the output capacitor CL as close to the IC as possible.
