SSL5031BTS  
Compact high power factor/low-THD buck LED driver IC  
Rev. 2 — 11 March 2015  
Product data sheet  
1. General description  
The SSL5031BTS is a highly integrated, high-precision, non-isolated buck controller with  
external MOSFET. It is intended to drive LED lamps in universal mains non-dimmable  
lighting applications up to 25 W. The SSL5031BTS is designed for high power  
factor/low-THD applications.  
The SSL5031BTS operates in Boundary Conduction Mode (BCM) with on-time regulation.  
Operating in BCM provides a constant output current control with high accuracy. Adaptive  
switching frequency gives freedom to choose the inductor, which enables the optimization  
of inductor size, efficiency and EMI.  
The SSL5031BTS starts up and operates in switching mode directly from an external  
resistor without dV/dt supply or auxiliary supply. This feature simplifies the VCC supply. It  
allows a low-cost off-the-shelf inductor to be used, providing flexibility in application  
design.  
The SSL5031BTS comes in a compact TSOP6 package.  
The SL5021BTS is suitable for Low-ripple applications. The SSL5031CTS is best for high  
power factor/Low-THD applications without high temperature foldback function.  
2. Features and benefits  
Driving LED strings from a rectified mains supply, high power factor/low-THD  
Small electronic Bill of Materials (BOM) enabling a compact solution and a small,  
single layer Printed-Circuit Board (PCB) footprint  
Excellent line and load regulation and LED output current accuracy  
Efficient BCM operation with:  
Minimal reverse recovery losses in freewheel diode  
Zero Current Switching (ZCS) and valley switching for switch turn-on  
Minimal inductance value and size required  
High efficiency (up to 91 %)  
Ultra low IC current during operation (< 150 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)
