Compact high power factor/low-THD buck LED driver

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 VCC supply. 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 curre.
