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. To provide a low-cost driver design, an off-the-shelf inductor can be used, which

provides flexibility in application design.
