Secondary Side Dimmable Constant Current (CC) and Constant Voltage (CV) Controller
The LD8115 is an isolation secondary LED constant current and constant voltage controller.
It provides the secondary side direct dimming interface by DC level and PWM duty single for smart LED 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 allows with its small footprint to minimize the PCB size as well as component counts.
The IC is available in SMD. LD8115 GS in SOP-8 package.
