- AN-2034 LM3445 -120VAC, 8W Isolated Flyback LED Driver (Rev. C)PDF, 24.5 Мб, Версия: C, Файл опубликован: 1 май 2013
This demonstration board highlights the performance of a LM3445 based Flyback LED driver solution that can be used to power a single LED string consisting of 4 to 8 series connected LEDs from an 90 VRMS to 135 VRMS, 60 Hz input power supply. The key performance characteristics under typical operating conditions are summarized in this application report. - 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 - AN-2069 LM3445 - 230VAC, 6W- 15W Isolated Flyback LED Driver (Rev. B)PDF, 2.8 Мб, Версия: B, Файл опубликован: 23 ноя 2010
