SSL21151T - Low-cost non-dimmable LED driver IC

This page provides the datasheet information for the SSL21151T, a member of the SSL2115x Low-cost non-dimmable LED driver IC family.

Description

The SSL2115X is a low-cost non-dimmable LED driver IC.

It is designed to drive LEDs in isolated flyback or non-isolated buck-boost topologies.

The device includes a high-voltage power switch and a circuit enabling start-up directly from the rectified mains voltage.

Features

  • Compact solution with a small form factor and a low component count.
  • Ease of integration.
  • Primary side sensing (no optocoupler required).
  • True current source behavior:.
  • LED current independent of mains voltage, LED voltage and temperature variation.
  • LED current accuracy (10 %).
  • Line regulation: 3 % at 230 V 10 %.
  • Load regulation: 3 % between 0.5  Umax and 0.85  Umax.
  • Efficiency up to 86 % depending on the.
