... The V and V storage capacitors must be chosen care- fully to insure low ripple and stable operation. The LT1330 charge pump operates in a power efficient Burst Mode operation. When storage capacitor voltage drops below a preset threshold, the oscillator is gated on until V are boosted up to levels exceeding a second threshold. ...
