RX is in Ohms, CX is in farads, VDD and VSS in volts, PWout in seconds.
7. If CX > 15 µF, Use Discharge Protection Diode DX, per Fig. 9.
8. The formulas given are for the typical characteristics only at 25
_C.
9. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
