SSL21081T/2T/3T/4T GreenChip drivers for LED lighting Rev. 2 — 6 December 2011 Preliminary data sheet 1. General description The SSL2108X is a range of high-voltage Integrated Circuits (ICs), intended to drive LED lamps in general lighting applications. The main benefits of the product family are: • • • • Small Printed-Circuit Board (PCB) footprint, and compact solution High efficiency (up to 95 %) Ease of integration Low electronic Bill Of Material (BOM) The product family is made of ICs with a range of internal HV switches for easy power scaling. The ICs work as boundary conduction mode converters, typically in buck configuration. The IC range has been designed to start up directly from the HV supply by an internal high-voltage current source. Thereafter, the dV/dt supply is used with capacitive coupling from the drain, or any other auxiliary supply. This functionality provides full flexibility in the application design. The IC consumes 1.3 mA of supply current with an internal clamp limiting the supply voltage. www.DataSheet.net/ The ICs provide accurate output current control with LED current accuracy within 5%. The ICs can be operated using Pulse-Width Modulation (PWM) dimming and has many protection features including easy LED temperature feedback. 2.
