产品描述

The SSL5251T is a highly integrated, high-precision dimmable controller with an externalMOSFET. 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.

The SSL5251T operates in Boundary Conduction Mode (BCM) with on-time control. It providesa constant output current control with good LED output current accuracy. Adaptiveswitching frequency gives freedom to choose the inductor, which enables the optimizationof inductor size, efficiency and EMI.

The SSL5251T can start up and operate in switching mode directly from an externalresistor without capacitor charge pump supply or auxiliary supply. This featuresimplifies the VCC supply. So, a low-cost off-the-shelf inductor can be used,which provides flexibility in application design.

产品特性和优势
  • Supports most available dimming solutions
  • Deep dimming level
  • Flicker-free dimming
  • Low component count ensuring a compact solution and small, single layer Printed-Circuit Board(PCB) footprint
  • Excellent line regulation and load regulation and good LED output currentaccuracy
  • Efficient BCM operation with:
    • Minimal reverse recovery losses in freewheel diode
    • Zero Current Switching (ZCS) and Valley switching for turn-on of switch
    • Minimum inductance value and size required
    • High efficiency (up to 88 %)
    • Ultra low IC current during operation (< 200 μA)
  • Many auto-recovery protections:
    • UnderVoltage LockOut (UVLO)
    • Cycle-by-cycle OverCurrent Protection (OCP)
    • Internal OverTemperature Protection (OTP)
    • Output OverVoltage Protection (OVP)
    • Output Short Protection (OSP)
  • Extended IC lifetime
产品应用
  • The SSL5251T is intended for low-cost, non-isolated dimmable lighting applications that workfrom single mains voltage.
