LED Driver, Triple Output, RGB, I2C Controlled

Overview

TopologyOther Topology
IC revision1.0

Description

The NCP5623B mixed analog circuit is a triple output LED driver dedicated to the RGB illumination or backlight LCD display. The built in DC to DC converter is based on a high efficient charge pump structure with operating mode 1x and 2x. It provides a 94 percent peak efficiency. The tiny package makes the device suitable for room limited portable applications.

Features

  • 2.7 to 5.5 V Input voltage range
  • RGB function fully supported
  • Programmable Integrated Gradual Dimming
  • 90 mA Output Current Capability
  • 94% Peak efficiency
  • Built-in Short Circuit Protection
  • Provides three independent LED drives
  • Support full I2C protocol
  • Embedded OVP / Open Load protection

Typical applications

  • Multicolor Illuminations/ Portable Back Light/ Digital Cellular Phone Camera Photo Flash/ LCD and Key Board simultaneously drive
