Product Description

The NCP1729SN35T1G is a switched-capacitor CMOS charge-pump Voltage Inverter designed for operation over an input voltage range of 1.5 to 5.5V with an output current capability in excess of 50mA. The operating current consumption is only 122µA and a power saving shutdown input is provided to further reduce the current to a mere 0.4µA. The device contains a 35kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26R and a voltage conversion efficiency of 99%. This device requires only two external 3.3µF capacitors for a complete inverter making it an ideal solution for numerous battery-powered and board level applications. The charge-pump converter inverts the voltage applied to the Vin pin. Conversion consists of a 2-phase operation.
Charge pump capacitor losses due to equivalent series resistance
I²R Losses due to the on-resistance of the MOSFET switches on-board the charge pump
