The SSL5251T is a highly integrated, high-precision dimmable controller with an external MOSFET. It is intended to drive LED lamps in dimmable lighting applications up to 25 W. The SSL5251T is designed for high power factor, phase-dimmable applications.\nThe SSL5251T operates in Boundary Conduction Mode (BCM) with on-time control. It provides a constant output current control with good LED output current accuracy. Adaptive switching frequency gives freedom to choose the inductor, which enables the optimization of inductor size, efficiency and EMI.\nThe SSL5251T can start up and operate in switching mode directly from an external resistor without capacitor charge pump supply or auxiliary supply. This feature simplifies the VCCsupply. So, a low-cost off-the-shelf inductor can be used, which provides flexibility in application design.
