Application Datasheet
1. General description
This application is an example circuit of 4 lamps inverter using DT8211. The design
contains protection functions such as OLP, OVP, SCP and basic functions such as
ADIM (Analog Dimming) and BDIM (Burst Dimming). This design is intended to show
how to use DT8211, implement basic functions and protection functions, and design
a circuit. This document contains features, schematic, and bill of materials.
