SM6704A - 4-Channel Constant Current LED Driver

Datasheet Summary

Description

The SM6704A is a 4-channel constant current LED driver that has a wide range of output current from 20mA to 180mA per channel and through an external resistor (Rext) to set the maximum sink current which gives users flexibility in controlling the light intensity of LEDs.

Features

  • 4-Channel constant sink current.
  • Constant output current invariant to load voltage change.
  • Maximum output current per channel up to 180mA.
  • Output current adjusted through an external resistor.
  • Excellent output current accuracy : - Between channels: ±3% , and - Between ICs: ±6% (Max. ).
  • Protected functions: - Over temperature (150℃ shutdown IC) - String short circuit detection.
  • Low dropout current source (0.6V at 180mA).
  • LED output voltage up to 50V.
  • S.

4-Channel Constant Current LED Driver SM6704A GENERAL DESCRIPTION The SM6704A is a 4-channel constant current LED driver that has a wide range of output current from 20mA to 180mA per channel and through an external resistor (Rext) to set the maximum sink current which gives users flexibility in controlling the light intensity of LEDs. In addition, users can precisely adjust LED brightness from 0% to 100% via OE control pin using popular pulse width modulation (PWM) signal. Low output voltage drop operation of 0.6V at 180mA allows for more power efficient designs across wider supply voltage range, the 4 LED pins are compatible with high voltage up to 50V supporting applications with long strings of LEDs.
