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 pact 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.
