Dimmable LED controller IC
- Parameters
- Features
- Description
- Superb mains-dimmable LED driver solution (both leading and trailing edge phase cut dimmers)
- Flyback or buck controller-only with external MOSFET
- Supports tapped-buck topologies to extend the Vf LED range
- Power-efficient boundary conduction mode
- Start-up JFET
- High power factor (>0.9)
- Full range of internal protections
- Compatible with wall switches with built-in indication light during standby
- “A” versions without short winding protection
- Benchmark dimmer compatibility per watt
- Compact, single-stage LED driver solution lowers eBOM cost
- Optimized, high-efficiency operation improves total lumen output per watt, lowering energy consumption further
