NCP1729

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,damage may occur and reliability may be affected.
*ESD Ratings
ESD Machine Model Protection up to 200 V, Class B
ESD Human Body Model Protection up to 2000 V, Class 2

    The NCP1729 is a CMOS charge pump voltage inverter that is designed for operation over an input voltage range of 1.15 V to 5.5 V with an output current capability in excess of 50 mA. The operating current consumption is only 122 A, and a power saving shutdown input of the NCP1729 is provided to further reduce the current to a mere 0.4 A. The device contains a 35 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26   and a voltage conversion efficiency of 99%. This device requires only two external 3.3F capacitors for a complete inverter making it an ideal solution for numerous battery powered and board level applications. The NCP1729 is available in the space saving TSOP−6 package.
