LM3404MREVAL
概述
The LM3402/02HV and LM3404/04HV are buck regulator derived controlled current sources 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 0.5A (LM3402/02HV) or 1.0A (LM3404/04HV). This evaluation board demonstrates the enhanced thermal performance of the PSOP-8 package option of any of those four ICs. The LM3404HV was chosen for the example circuit because the combination of high output current, high input voltage, and high duty cycle create the greatest demand for low junction-to-ambient thermal resistance (ΘJA). Note that the LM3404/04HV in SO-8 can also be used with this evaluation board, with reduced thermal performance.
