Its rugged design is optimized for driving LED banks directly from the main utility line eliminating external components by merging them into a monolithic package, drastically reducing the board space and cost. The thermal turndown located in the center of the IC protects itself from operating in atypical conditions. The voltage shutdown protection circuit safeguards the IC and the system’s LEDs from voltage surges that can overstress the system.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. 2. 1msec half sine wave superimposed on rated load 3. Power dissipated from junction to lead PCB mounted on suggested PAD Layout. Derate 20mW/°C when the ambient temperature is above 25 °C. Special care of the thermal dissipation in the PCB design must be taken. 4. ESD protection. HBM : 1kV at all Pins. LS9100-170306-3 °C Electrostatic Discharge Sensitivity This integrated circuit can be damaged by ESD. LSI/CSI recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 7 6 5 HS LS1 LS0 RS0 RS1 RS2 2 3 4 L 8 N L2 Surge Protection CKT L1 110VAC 60HZ 1 Typical Application Rsns DANGER!: THE READER IS WARNED THAT CAUTION MUST BE USED IN THE CONSTRUCTION, TESTING AND USE OF THIS CIRCUIT.

LS9100-170306-6 Package Mounting The figure below provides the minimum recommended PCB layout for the LS9100 device. For lowest overall thermal resistance, it is best to solder the heat sink Pad directly to the circuit board. Adding more area to the heat sink improves heat dissipation. 0.05 0.600 Solder mask over copper 0.112 Top Side 0.096 0.05 0.05 0.600 0.022 10x 0.012 Via Plated holes 0.132 Bottom Side 0.600 Notes: A.
