The LM3450A evaluation board is designed to provide an AC to LED solution for a 30 W LED load. Specifically, it takes an AC mains input and converts it to a constant current output of 700 mA for a series string of 1 to 13 LEDs (maximum LED stack voltage of 45 V). There are two assembly versions designed to operate from two different nominal AC input voltages, 120 VAC or 230 VAC.

This document describes an isolated, power factor corrected, very high efficiency LED driver (non-dimmable) designed to drive an LED string of 30 V at a current of 500 mA (both nominal) from an input voltage range of 90 to 265 VAC. The design employs an active ripple filter to achieve less than 30% output ripple. A reference board DER-284 was used with active ripple filter daughter board.

The RT7310 is a high power factor constant current LED driver which is optimized for the compatibility with phase-cut dimmers. It supports high power factor across a wide range of line voltages, and it drives the converter in the Quasi-Resonant (QR) mode to achieve higher efficiency.

This EVM uses the TPS92010 high efficiency offline LED lighting driver controller. The power topology is a quasi resonant mode flyback. This makes for a cost competitive solution. This TPS92010 EVM implements a constant current, high efficiency, low ripple AC-DC LED lighting driver.
