SSL5031TS

SSL5031TS Compact buck-boost LED driver IC Rev. 1.1 — 31 March 2016 Product data sheet 1. General description The SSL5031TS is a highly integrated, high-precision, non-isolated MOSFET buck-boost controller. It is intended to drive LED lamps in universal mains non-dimmable lighting applications up to 25 W. The SSL5031TS 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 SSL5031TS starts up directly from an external resistor without dV/dt supply or auxiliary supply. It operates in switching mode. This feature simplifies the VCC supply. It allows a low-cost off-the-shelf inductor to be used, providing flexibility in application design. The SSL5031TS comes in a compact TSOP6 package. The SSL5021BTS is suitable for low-ripple buck applications. The SSL50...
