SSL5237TE Mains dimmable buck-boost LED driver IC 10 Ohm/700 V Rev. 1 — 13 March 2015 Product data sheet 1. General description The SSL5237TE 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 SSL5237TE is designed to achieve high power factor, phase-dimmable applications. The SSL5237TE operates in Boundary Conduction Mode (BCM) with constant 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.
