Description:

Constant frequency 1x/1.33x charge pump DC/DC converter

Features

* VIN Range: 2.5V to 5.5V Fully Programmable Current with Single Wire

Applications

* The ET9378 is capable of driving up to eight channels of LEDs at preset 19mA per channel from a 3.3V to 5.5V input. Under the same conditions, when the charge pump is opened, its efficiency is 10% higher than the conventional 1.5X charge pump. The current sinks may be operated individually parallel
