General Description

Features



Secondary-Side Constant Current and Voltage

The LD8115A 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.

Feedback



High Accuracy 200mV (+/-2%) of LED Current

Threshold Control



Precision 1.25V Reference Voltage ( +/-1%)

Low operation current ( < 0.5mA)

Wide VCC Operation Range 3.6~38V

Precision Secondary-side LED current Dimming with

Analog and PWM

The device features include wide input voltage range from

3.6V to 38V, high-accuracy LED operation current and

output constant voltage.

Analog Dimming : 0.1V~2.5V

PWM: 500Hz~30kHz

Applications

The LD8115A is the SOP-8 package to minimize the PCB

size as well as component counts.
