Doubler Charge Pump IC

ꢀGENERALDESCRIPTION

PACKAGE OUTLINE

The NJW4190 is the doubler charge pump IC that operates wide

5V to 17V input range. With only the external part of an input/output

capacitor and a charge pump capacitor, can compose the doubler

voltage circuit. It has a high current capability and a corresponding

to small-sized capacitor compared with conventional product such

as popular 7660/7662.

NJW4190R

NJW4190M

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

function and external synchronous function.

The NJW4190 is suitable for the bias voltage of CCD, sensors

and operational amplifiers.

There is the NJW4191 for inverter voltage output application.
