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. Also several fine tuning options are available for differentiation purposes. The chip also has an unique AGC (Automatic Gain Control) feature which tracks the input signal level and automatically adjusts the gain to an optimal value.

The LP3950 has a high efficiency magnetic DC/DC converter with programmable output voltage and switching frequency. The converter has high output current capability so it is also able to drive flash LEDs in camera phone applications.

The LP3950 is similar to LP3933 and LP3936 in that the color LEDs (or RGB LEDs) can also be programmed to generate light patterns (programmable color, intensity, on/off timing, slope and blinking cycle).

All functions are software controllable through a SPI or I2C compatible interface but the device also supports one pin control for enabling predefined (default) audio synchronization mode.

Reliability Metrics

Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)
LP3950SL CMOS7 0 16561 0 0 954000 4 270700104
LP3950SLX CMOS7 0 16561 0 0 954000 4 270700104

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
