    PDF, 146 Kb, Revision: A, Datei veröffentlicht: May 1, 2013
    The LM3404/04HV is a buck-regulator designed for driving high powered LEDs at forward currents of upto 1.0A. LED drivers often experience thermal conditions that are extreme even by the standards ofswitching converters. For example, LED drivers are often placed on the same metal-core PCB (MCPCB)as the LEDs themselves. At 1.0A, a single-die white LED can dissipate more than 3W. The temperatur

    PDF, 76 Kb, Revision: A, Datei veröffentlicht: May 1, 2013
    The constant on-time (COT) control method used by the LM3402 and LM3404 constant-current buckregulators provides a balance between control over switching frequency and fast transient response.Normally this "quasi-hysteretic" control senses the input voltage and adjusts the on-time tON of the powerMOSFET as needed to keep fSW constant. Investigating a little more deeply reveals that tON is in

    The world seems to be poised to make the leap to LED lighting. Incandescent has been deemed tooinefficient, which it is, and fluorescent lighting often does not achieve the lifetime it claims. Fluorescentalso has another set of baggage, dangerous chemicals. So the logical choice that most people believe cantake the crown is high brightness (HB) LEDs. HBLEDs are becoming more attractive as th

    PDF, 171 Kb, Revision: A, Datei veröffentlicht: May 3, 2013
    Using a switching regulator as an LED driver requires the designer to convert a voltage regulator into acurrent regulator. Beyond the challenge of changing the feedback system to control current, the LEDsthemselves present a load characteristic that is much different than the digital devices and other loads thatrequire constant voltage.
