LED Lighting Drivers Dimmable LED Driver,12-SOIC Package,low current

The SSL21084T is a high-voltage Integrated Circuit (IC) for driving retrofit LED lamps in general lighting applications. It enables the implementation of a very compact low-cost
system solution. The IC incorporates an integrated internal HV switch and works as Boundary Conduction Mode (BCM) buck converter.

The SSL21084T is supplied by a start-up bleeder resistor, a dV/dt supply using capacitive
coupling from the drain or any other auxiliary supply. The IC supply current is low. An
internal clamp limits the supply voltage.
The IC has accurate output current control and can be operated using Pulse-Width
Modulation (PWM) dimming. In addition, several protection features are available such as
easy external temperature feedback.

The main benefits of SSL21084T/1
• Small Printed-Circuit Board (PCB) footprint and compact solution
• High efficiency (up to 90 %) for non-dimmable high power factor solutions
• High power factor (>0.9)
• Ease of integration and many protection features
• Low electronic Bill Of Material (BOM)
• Mains phase-cut dimmable using external components
• Highly flexible IC for use in buck, buck/boost modes
• Single inductor used for non-isolated configurations because of internal demagnetization detection and dV/dt supply

The IC range is designed to start up directly from the HV supply using an internal high-voltage current source. An internal clamp limits the supply voltage.

Applications
The SSL21084T are intended for mains dimmable compact LED lamps for single mains input voltages. Mains input voltages include 100 V (AC), 120 V (AC) and 230 V (AC).
