NJW4191 Inverting Charge Pump IC GENERAL DESCRIPTION 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. 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. PACKAGE OUTLINE NJW4191R NJW4191M FEATURES Inverted Output -17V max.
