LD8115
LD8115 is Secondary-side Dimmable Constant Current and Voltage Controller manufactured by Leadtrend Technology.
Description
The LD8115 is an isolation secondary LED constant current and constant voltage controller, and provide the secondary-side direct dimming interface by DC level and PWM duty single for smart LED lighting application.
The device features include wide input voltage range from 3.6V to 38V, high-accuracy LED operation current and output constant voltage.
The LD8115 is the SOP-8 package to minimize the PCB size as well as ponent counts.
