Description

The LM3549SQ/NOPB is a high-performance, versatile LED driver from Texas Instruments, a leading global semiconductor company.

  • Wide Input Voltage Range: Operates from a 2.7V to 5.5V input voltage range.
  • High-Frequency Boost Converter: Provides a constant current to drive up to 8 white LEDs in series.
  • Advanced Brightness Control Capability: Offers both analog and pulse width modulation (PWM) brightness control.
  • Excellent Thermal Management: Features an internal thermal shutdown protection mechanism.
  • Under-Voltage Lockout (UVLO): Shuts down the device when the input voltage falls below a predefined threshold.
  • Compact Size: Packaged in a 24-pin LLP.
  • RoHS Compliant: Free from hazardous substances.
