... NXP Semiconductors 8. Functional description The SSL2101 is a LED driver IC that operates directly from the rectified mains. The SSL2101 uses on-time mode control and frequency control to control the LED brightness. The BRIGHTNESS and PWMLIMIT input of the IC can be used to control the LED light output in combination with an external dimmer. The PWMLIMIT input can also be used for Thermal Lumen Management (TLM) and for precision LED current control ...

... NXP Semiconductors 8.4 Bleeder for dimming applications The SSL2101 IC contains some circuitry intended for mains dimmer compatibility. This circuit contains two current sinks that are called bleeders. A strong bleeder is used for zero-cross reset of the dimmer and TRIAC latching. A weak bleeder is added to maintain the hold current through the dimmer ...
