Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

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. 

The 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. 

Features and benefits

 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 current accuracy

 Efficient BCM operation with:

 Minimal reverse recovery losses in freewheel diode

 Zero Current Switching (ZCS) and Valley switching for turn-on of switch

 Minimal inductance value and size required

 High efficiency (up to 88 %)

 Ultra low IC current during operation (< 200 A)

 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 lifetim

Applications

 The SSL5251T is intended for low-cost, non-isolated dimmable lighting applications that work from single mains voltage.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
