| Abstract: Maxim > App Notes > POWER-SUPPLY CIRCUITS Keywords: Charge Pump Doubles Negative Voltage Aug 27, 2001 APPLICATION NOTE 782 Charge Pump Doubles Negative Voltage For low-power dc-dc circuits, the , applications. The absence of such ICs designed for negative voltage, however, requires that you adapt an , negative voltage to be doubled. The resulting circuit requires only three external capacitors to double a negative voltage between 2.0V and 5.5V. Figure 2. This circuit (a modification of Figure 1) doubles ... | Original |
