SSL21081 LED驅(qū)動器參考板

This document describes the performance, technical data and connection of the SSL21081 reference board. The SSL2108X series is an NXP Semiconductors driver IC intended to provide a low cost, small form factor LED driver. This board is intended to operate at 100 V (AC) or 120 V (AC), using an output voltage greater than 30 V.

The SSL21081 is a highly integrated switching mode LED driver which enables constant current driving from the AC mains input in a standard SO8 package. It is a solution for small LED retrofit lamp applications, especially those applications for low-power factor designs.

The SSL21081 supports buck converter topology and is suitable for non-isolated, non-dimmable LED retrofit lamps. It can drive a long LED string, up to a 70 V forward voltage and is most efficient in this type of LED module. The SSL2108 series is intended to operate at high output voltages.

This reference board is an example that can be used in applications up to E17 form factor lamp fittings.

This reference board is connected to a high AC voltage. Avoid touching the reference board during operation. An isolated housing is mandatory when used in uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a fixed or variable transformer (Variac) is always recommended.
