A8442 - 80mA 4-CHANNEL CHARGE PUMP WHITE LED DRIVER

A8442 Description

AiT Semiconductor Inc.www.ait-ic.com A8442 80mA 4-CHANNEL CHARGE PUMP WHITE LED DRIVER WITH LOW DROPOUT CURRENT SOURCE .
FEATURES The A8442 is a high performance white LED driver.

A8442 Features

* The A8442 is a high performance white LED driver. It integrates current sources and automatic mode selection charge pump. The part maintains the high efficiency by utilizing an x1/x1.5 fractional charge pump and low dropout current sources. The small equivalent x1 mode open loop resistance and ultr

A8442 Applications

* The A8442 supports up to 4 white LEDs and regulates a constant current for uniform intensity. The part implements a 4-bit DAC for brightness control. Users can easily configure the LED current from 1.25mA to 20mA by a serial pulse. The dimming of white LEDs current can be achieved by applying a pul
