Description
LIS8516 is a control chip dedicated to LED constant current drive. By adopting the proprietary primary side LED constant current control technology, the system architecture has been simplified to the greatest extent.
It not only saves the feedback devices such as optocoupler and 431 required for traditional secondary side control, but also further saves the auxiliary winding, feedback resistor and rectifier diode for IC power supply in traditional primary side control architecture. Passive components, so that the system cost has been greatly reduced.
