SSL5257TE Mains dimmable buck-boost LED driver IC 10 Ohm/700 V Rev. 2 — 11 September 2015 Product data sheet 1. General description The SSL5257TE is a highly integrated, high-precision buck-boost controller with an internal MOSFET. It is intended to drive low-cost compact dimmable LED lamps up to 10 W. The SSL5257TE is designed to achieve high power factor, phase-dimmable applications. The SSL5257TE operates in Boundary Conduction Mode (BCM) with on-time control. It regulates a constant output current over line and load variations. The wide switching frequency range makes it possible to choose an inductor, which enables the optimization of inductor size, efficiency and EMI. The SSL5257TE can start up and operate in switching mode directly from the rectified mains.
