NJW4191 Datasheet Inverting Charge Pump

Manufacturer: New Japan Radio

Datasheet Details

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.
