TEXAS INSTRUMENTS LM3404EVAL

Product Overview

The LM3404EVAL is an evaluation board for LM3404, a buck regulator derived controlled current source designed to drive a series string of high power, high brightness LEDs (HBLEDs) such as the Luxeon K2 Emitter at forward currents of up to 1A. The converter output voltage adjusts as needed to maintain a constant current through the LED array. The LM3404 is a true step down regulator with an output voltage range extending from a VO(MIN) of 200mV (the reference voltage) to a VO(MAX) determined by the minimum off time (typically 300ns). It can maintain regulated current through any number of LEDs as long as the combined forward voltage of the array does not exceed VO(MAX).
  • Integrated 1A MOSFET
  • Vin range from 6V to 42V
  • 1.2A output current over temperature
  • Cycle by cycle current limit
  • No control loop compensation required
  • Separate PWM dimming and low power shutdown
  • Supports all ceramic output capacitors and capacitor less outputs
  • Thermal shutdown protection
