LED DRVR 9V/12V 8-Pin SO T/R

The SSL2109T, a controller-only device used to drive an external switch, is for applications up to 25 W (external MOSFET selection enables flexibility on efficiency and system cost) and extends the feature set with high power factor (>0.9), universal mains, and isolated topologies.

• Flyback or Buck controller-only with external MOSFET
• Power-efficient boundary conduction mode
• Tight LED current regulation: better than 5%
• Direct PWM dimming possible
• Fast transient response via cycle-by-cycle control
• No need for binning on LED forward voltage
• Full set of internal protections
• Simple design-in
• Support for high power factor (>0.9) and universal mains
• High efficiency: up to 95% measured on reference board
• Low bill of materials: only 14 components for full application
• Easy, low-cost manufacturing at high volumes
• High reliability: IC lifetime easily matches or surpasses LED lamp lifetime
