Demonstration circuits 1511A-A and 1511A-B feature the LTM®8042 and the LTM8042-1, which are respectively complete 1A and 350mA µModule LED drivers. The demonstration circuits are assembled as boost topologies, accepting an input voltage from 3V to 30V and supporting an output up to 32V (see Table 1).

The NCL30186SMRTGEVB Evaluation Board is an AC-DC power factor corrected flyback controller targeting isolated and non-isolated “Smart-dimmable” constant current LED drivers. The controller operates in a quasi-resonant mode to provide optimal efficiency. The current control algorithm supports flyback, buck-boost, and SEPIC topologies. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side.

The LM3404HV was chosen for the example circuit because the combination of high output current, high input voltage, and high duty cycle create the greatest demand for low junction-to-ambient thermal resistance (θJA). Note that the LM3404/04HV in SO-8 can also be used with this evaluation board, with reduced thermal performance.

The document describes a high power-factor corrected dimmable LED driver designed to drive 21 V at 0.33 A from an input voltage range of 90 VAC to 265 VAC. The LED driver utilizes the LNK403EG from Power Integrations.

This document describes an isolated, power factor corrected, very high efficiency LED driver designed to drive a 30 V LED string at a current of 500 mA (nominal). The input voltage range is 90 VAC to 265 VAC. The LED driver uses a LNK417EG device from the LinkSwitch-PH family of ICs.
