Inverting Charge Pump IC

ꢀGENERALDESCRIPTION

PACKAGE OUTLINE

The NJW4191 is the inverting charge pump IC that operates

wide 4.7V to 17V input range. With only the external part of an

input/output capacitor and a charge pump capacitor, can compose

the inverting voltage circuit. It has a high current capability and a

corresponding to small-sized capacitor compared with conventional

product such as popular 7660/7662.

NJW4191R

NJW4191M

For usability, it has ON/OFF function, Output Voltage Adjustable

function and external synchronous function.

The NJW4191 is suitable for the bias voltage of a liquid crystal

panels, CCD, sensors and operational amplifiers.

There is the NJW4190 for doubler voltage output application.
