Manufacturer: New Japan Radio

Overview: NJW4190 Doubler Charge Pump IC GENERAL.

Download the NJW4190 datasheet PDF. This datasheet also includes the NJW4190-1 variant, as both parts are published together in a single manufacturer document.

General Description

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.
