SSL5031CTS

Compact high power factor/low-THD buck LED driver IC

Rev. 2 — 11 March 2015

Product data sheet

1. General description

The SSL5031CTS 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 SSL5031CTS is designed for high power

factor/low-THD applications.

The SSL5031CTS 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 SSL5031CTS starts up and operates in switching mode directly from an external

resistor without dV/dt supply or auxiliary supply. This feature simplifies the V_CCsupply. It

allows a low-cost off-the-shelf inductor to be used, providing flexibility in application

design.

The SSL5031CTS comes in a compact TSOP6 package.

The SSL5031BTS is best suited for high power factor/low THD applications with a

high-temperature foldback function. The SSL5021BTS is suitable for low-ripple

applications.

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)
