Single String > 100 W
PFC + LLC stage - Constant Current (CC)
DC/DC Buck (CC) for Non-SELV Applications
Single String < 100 W
PFC/FB stage - Constant Voltage (CV) + Secondary Buck
Infineon offers analog and digital solutions for the AC-DC LED control. Analog solutions include the IRS2982S analog flyback controller IC and the 800 V CoolMOS™ P7, which make the perfect fit for single string topologies <100W. For digital solutions, the XDP™ LED XDPL8105 digital flyback controller IC is recommended, while the CDM10V is perfect for easy and flexible implementation of dimming functionalities. 650V/700V CoolMOS™ CE and 600V-800V CoolMOS™ P7 are the right power switches for your LED driver.

Tuning in Full Color
One of the XMC™ application-specific features for lighting is a brightness and control unit (BCCU) that simplifies digital LED dimming and eases color control applications. It is specifically designed to automatically control the dimming level and color of multichannel LED lamps, requires little user code, and supports completely flicker-free operation owing to its 12-bit pulse density modulation (PDM) dimming signals. The exponential dimming engine provides automatic gradual brightness change and invisible dimming steps.
