LP3950 - Color LED Driver

Description

The LP3950 is a color LED driver with a built-in audio synchronization feature for any analog audio input such as polyphonic ring tones and MP3 music.

LEDs can be synchronized to an audio signal with two methods - amplitude and frequency.

Features

  • 1.
  • 2 Audio Synchronization for Color LEDs with Two Modes: Amplitude and Frequency.
  • Programmable Frequency and Amplitude Response with Tracking Speed Control.
  • Automatic Gain Control or Selectable Gain for Input Signal Optimization.
  • RGB Pattern Generator Similar to LP3933/LP3936.
  • Magnetic DC-DC Boost Converter with Programmable Boost Output Voltage.
  • Selectable SPI or I2C Compatible Interface.
  • One Pin Default Enable for Non-Serial Interf.
