- AN-1656 Design Challenges of Switching LED Drivers (Rev. A)PDF, 171 Kb, Revisión: A, Archivo publicado: mayo 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. The LED WEBENCHВ® online design environment predicts and - AN-2102 LM3464 and LM5021 DHC 25W Reference Designs (Rev. A)PDF, 8.3 Mb, Revisión: A, Archivo publicado: mayo 1, 2013
This evaluation board consists of a Texas Instruments LM5021-based 120Vac 24W AC/DC flybackconverter and a LM3464-based dynamic head room control (DHC) four channel LED driver IC. Thisdemonstration platform was developed so that the customers could evaluate the LM3464 with an AC/DCsupply.
