Application Notes
- Thermal Performance of the LM3404/04HV in SO-8 and PSOP-8 Packages (Rev. A)PDF, 146 Кб, Версия: A, Файл опубликован: 1 май 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 - AN-1853 COT Drivers Control LED Ripple Current (Rev. A)PDF, 76 Кб, Версия: A, Файл опубликован: 1 май 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 - AN-1982 Small, Wide Input Voltage Range LM2842 Keeps LEDs Cool (Rev. A)PDF, 60 Кб, Версия: A, Файл опубликован: 23 апр 2013
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 - Driving LEDs: To Cap or Not to CapPDF, 542 Кб, Файл опубликован: 21 мар 2007
- AN-1656 Design Challenges of Switching LED Drivers (Rev. A)PDF, 171 Кб, Версия: A, Файл опубликован: 3 май 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. The LED WEBENCHВ® online design environment predicts and
