应用须知
- AN-1656 Design Challenges of Switching LED Drivers (Rev. A)PDF, 171 Kb, 修订版: A, 档案已发布: 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. The LED WEBENCHВ® online design environment predicts and
