  • Using the LM3643/4/8 in an Inductorless and/or Simplified PCB Routing Configurat
    PDF, 216 Kb, 档案已发布: Oct 11, 2016
    The LM3643, LM3644 and LM3648 are a family of high power LED flash drivers that can be used as alighting source in many applications ranging from a mobile phones front facing selfie flash to a flash lighton a handheld point of sale (POS) terminal. While each device is highly configurable, there are timeswhere the full feature set might not be needed or where the fine pitch of the device (0
  • Using Flash LED Drivers for Infrared (IR) LED Applications
    PDF, 163 Kb, 档案已发布: Mar 20, 2017
    The LM3643/4/8 devices are commonly used for mobile phone flash LED drivers. This application notediscusses the general applications of IR in mobile devices as well as the behavior of TI’s LM364X devicesfor such applications.These LED flash drivers are small solutions that provide a maximum of 1.5 A to one or two LEDs in eitherpass mode, where the current sources are connected to the input
