PRODUCTION DATA.
As a result of large recharge current flowing in and out of the four charge pump capacitors during charge pump discharge and recharge events, TI recommends placing bypass capacitors that are at least equal in value to the charge pump capacitor close to each supply voltage pin. A minimum of 2-µF bypass capacitors for each channel are required to minimize any transient appearing on the power supply because both positive and negative charge pump 1-µF bypass capacitors are recharged on the +12-V supply.
